Investigation: We tried to buy American chips as a Russian defense manufacturer — and it worked

Despite bans put in place by the U.S. and Europe on the supply of electronic components to Russia, dozens of Russian microelectronics suppliers continue to obtain and resell imported chips to Russian arms manufacturers successfully.

Without these Western chips, Russia would not be able to produce key weapons — like missiles, drones, and self-propelled howitzers.

To prove that this line of supply continues to operate three years into Russia’s full-scale invasion, the Kyiv Independent tried ordering American microchips from Russian trading companies, posing as a Russian defense producer.

We obtained a list of Russian firms supplying Western microcircuits to the Russian defense industry from leaked emails of the Russian state holding Ruselectronics. The Kyiv Independent obtained access to the leak together with OCCRP.

(The Kyiv Independent’s first investigation based on the leak is available here. The investigation focused on the continued export of Russian weapons during the full-scale war.)

We combed through the emails for mentions of the supply of American and European chips to Russia and followed the traces of the described transactions.

According to the leaked letters, after the start of the full-scale invasion, companies of the Ruselectronics holding requested large volumes of various American and European chips from Russian suppliers — and got confirmation that they could be supplied, despite sanctions. The leaked emails cover the first few months of the full-scale invasion in 2022.

Through the emails, the Kyiv Independent identified an ecosystem of companies that came to the aid of Ruselectronics holding by building new supply chains for banned components.

Using customs data, we also discovered a huge network of their foreign suppliers, mostly from China and Hong Kong.

These records, together with our undercover experiment, prove that American and European-branded chips continue flowing to Russia — the country that started the largest war in Europe since World War II.

Response to sanctions: Increase purchases of American chips

The U.S. and EU imposed sanctions and export restrictions immediately on the first day of Russia’s invasion of Ukraine on Feb. 24, 2022, and some even the day before. The restrictions, among other things, banned American and European chips from entering Russia, whose defense sector relies heavily on their use in producing weapons.

Russia wasn’t ready for it. From the leaked emails, it’s clear that the producers had no significant stockpile of chips.

On the second day of the invasion, one Ruselectronics employee emailed notes from an internal meeting to two colleagues. It mentions that ���delivery times for electronic components had increased, and prices had risen.”

The letter concludes that the holding would need to buy a year’s worth of stock of electronic components.

This and other emails suggest that the Russian arms manufacturer wasn’t preparing for a protracted war. It didn’t have extra stocks of imported chips at the start of the invasion but began procuring them immediately after the start of the invasion, bypassing the fresh restrictions.

In April 2022, two months after the start of the invasion, Ruselectronics companies prepared proposals on how to reduce the risks of disruptions in the procurement of electronic components.

Among other things, the proposals called for allocating additional funding to create stockpiles of electronic components.

But the leaked letters reveal that suppliers faced difficulties procuring the electronics.

In March 2022, Elitcom, a Russian supplier of Ruselectronics holding, wrote to say that it would fail to deliver chips produced by the American company Analog Devices on time. The contract for the chips was signed in December 2021, and one of Ruselectronics’ subsidiaries expected their delivery in May 2022.

Elitcom explained that due to the Russian invasion, the American manufacturer had stopped deliveries to Russia, and Analog Devices’ official distributor “did not confirm its readiness” to fulfill the contract.

But Elitcom had a plan and said it could arrange the supply of the necessary Analog Devices chips, despite sanctions. The company was offering to do so with the help of unnamed “foreign partners” who confirmed the chips would arrive in September-October 2022, several months later than originally planned.

Similar cases occurred across the sector. Around that same time, a Russian electronics supplier, TestKomplekt, emailed a Ruselectronics’ subsidiary to warn that due to foreign restrictions, it had revised the terms of supply of American-branded chips, such as Analog Devices, Texas Instruments, Microchip Technology, Altera, Maxim Integrated, and others. Not a problem — the company was still ready to supply them, but at new prices.

The leaked emails contain direct evidence that Russian defense manufacturers can’t produce weapons without Western chips, nor can they be substituted with analogs.

For example, a sanctioned Ruselectronics’ subsidiary, the Istok Research and Production Corporation, argued that it needed to purchase certain American chips produced by Analog Devices because Russian and other analogs “do not comply with the design documentation” of the enterprise.

The use of other chips “is impossible,” an internal note says.

“For the Russians, this stuff is absolutely critical,” explains James Byrne, senior associate fellow at the Royal United Services Institute (RUSI), a London-headquartered security think tank. “They can’t build missiles without it. It’s not like they’re just going to give up.”

But the Russian arms manufacturers didn’t have to give up the Western chips. There were those willing to supply them.

Invisible elements of a long supply chain

An unobvious but important detail illustrated by the leaked emails is that Russian arms manufacturers don’t import Western chips directly from abroad. They didn’t do so even before the full-scale invasion.

Instead, Russian arms manufacturers buy imported circuits within Russia.

Whenever they need electronics, they tap into a vast network of Russian suppliers of imported electronic components like Elitcom or TestKomplekt. The network is a mix of state-owned and private companies that specialize in purchasing American and European chips.

Some of them openly advertise the sale of American chips on their websites even now, in 2025, in the fourth year of the Russian war.

It was these companies that came to the rescue of the Russian defense industry after the introduction of unprecedented Western export bans and sanctions, setting up workarounds to supply chips to Russia.

These companies don’t publicly advertise that their clients are Russian defense manufacturers. It is only through internal correspondence and access to contracts, which aren’t public, that it becomes clear that these private firms with flashy websites are actually the lifeline of Russian missile production.

The leaked emails show that after the start of Russia’s full-scale war against Ukraine and the imposition of restrictions and sanctions, more than two dozen Russian providers of Western chips responded to Ruselectronics’ growing demand.

Among them were Russian companies Modern Digital Technologies, Imotek, Elsup, AST Components, Orion-Electronika, Altex, Elesar-Grupp, Trade House Alfa-Komplekt ECB, Communication Systems Equipment, RTKT, GC Electromir, MTG, Electronintorg, and others.

They confirmed their readiness to supply hundreds of different American-branded chips in response to requests from Ruselectronics’ subsidiaries in March–April 2022.

Some Russian chip suppliers took the initiative and approached representatives of Ruselectronics to advertise their capabilities, knowing they would struggle to obtain chips.

In March 2022, the Russian design center Kristal wrote a letter to a Ruselectronics representative, informing him that the company had supply channels for imported electronic components from Texas Instruments, Analog Devices, Maxim, Microchip, Micron, NXP, Xilinx (AMD), Qorvo, and Broadcom. Kristal offered a meeting to discuss cooperation.

“Together with foreign partners, we have access to global distributors of electronic components,” Kristal’s CEO Leonid Zotov boasted in an email sent on the 19th day of Russia’s full-scale war against Ukraine.

Who is behind suppliers like Kristal? Among the owners are a retired Russian major general, medium-sized entrepreneurs, a Russian oligarch, as well as employees of companies united in the state-owned Ruselectronics holding, or the Russian state defense corporation, Rostec, itself.

For example, Elsup’s owner is Vladislav Borodovitsyn. According to his Instagram page, he previously held a position as an employee of a research institute that is jointly controlled by Rostec and the investment company Sistema, owned by Russian oligarch Vladimir Yevtushenkov.

Electronintorg is part of the state-owned Rostec’s subsidiary Ruselectronics.

Among the co-owners of AST Components, we found the retired Russian Major General Magomed Tolboev, who was also an aspiring politician, and his son Ruslan.

Commercial proposals sent by Russian suppliers at Ruselectronics’ request included American electronic components used in Russian missiles and other weapons.

Among the offers, the Kyiv Independent identified a number of American chips that had been found in Kinzhals — Russian ballistic missiles that carry a warhead of nearly 500 kilograms used in strikes on Kyiv and more distant cities, killing civilians.

According to the leak, Russian intermediary companies were also ready to supply U.S. chips that are used in Russian Kalibr and R-77 missiles, as well as in the Tornado-G system capable of launching 40 rockets at once and in the Giatsint-S, a tank-mounted gun.

Although the leaked Ruselectronics’ emails don’t extend beyond May 2022, Russian intermediaries did not exhaust their ability to supply the Russian defense industry with Western chips.

The Kyiv Independent managed to obtain Russian tax records from 2024 with a list of contractors for one Ruselectronics’ subsidiary: the Istok Research and Production Corporation.

In 2024, Istok continued to receive supplies from the majority of the Russian providers of imported circuits that we encountered in the leaked emails.

The Kyiv Independent decided to try and order American chips through Russian suppliers in February 2025 — and was successful.

Buying American chips for Russian missiles

To confirm that the flow of Western chips to Russia is not a fiction, we carried out an undercover experiment.

The Kyiv Independent took on the role of an employee of a real Ruselectronics’ subsidiary, the Almaz research and production enterprise, which produces electronic systems for military equipment.

Surprisingly, the most difficult aspect of the experiment was to create an email account with a Russian email service, as they are blocked in Ukraine. When that was done, trying to buy banned Western chips in Russia was easy.

The Kyiv Independent prepared a request for a commercial proposal on behalf of Almaz, asking for circuits produced by American-headquartered companies, and sent the request to two dozen Russian suppliers of American chips.

Ten of them responded, confirming their ability to deliver the required chips.

The Russian companies Imotek, AST Components, Elsup, Altex, RTKT, and Vneshtekhsnab confirmed they were ready to deliver chips in 1.5 to three months.

Modern Digital Technologies, Electromir, and Imotek sent their offers, specifying the years of chip production. They included chips from Analog Devices, Texas Instruments, and Atmel manufactured in 2022-2024.

One of the Russian companies, Elesar-Grupp, sent a full list of the chips it currently had in its warehouse, indicating their quantity. There were millions of chips of famous American and European brands.

The list, provided to the Kyiv Independent when it reached out under the guise of an Almaz employee, included chips from American manufacturers Analog Devices, Texas Instruments, Microchip Technology, Xilinx (AMD), ON Semiconductor, Intel, Dutch NXP, German Infineon, and many others.

Among them were those used in Russian missiles and attack drones.

In the fourth year of Russia’s full-scale war in Ukraine, those American and European chips are still available to Russian intermediary firms, and through them — to Russian arms manufacturers.

Who is helping Russia circumvent the export bans on Western chips?

Due to strict export bans imposed after the start of the full-scale invasion, Western chipmakers have stopped direct deliveries to Russia and banned official distributors from supplying their parts to Russian companies.

Instead, Western chips enter Russia through third countries that have not imposed restrictions.

The main suppliers of American chips to Russia are China and Hong Kong.

Customs data since the start of the full-scale invasion in February 2022 shows that dozens of companies, mainly registered in Hong Kong and China, sent Western chips to Russian electronic component traders cooperating with Ruselectronics holding.

The companies are either Chinese providers of Western microelectronics with many years of experience or newly established entities without websites and public contact information.

According to ImportGenius, the Hong Kong-based electronic component seller Analog Technology has supplied Western chips to the Russian companies Modern Digital Technologies and Imotek since 2022.

Hong Kong-based Analog Technology was established in 2011 and positions itself as a seller of chips “of all famous worldwide brands.” It supplied all well-known American and European chip brands to Russian firms despite Western export restrictions, according to trade data.

Another Hong Kong-based company, Icscan Electronic, registered in 2022, presents itself as a “famous international one-stop purchasing service provider of electronic components,” and has sold chips of various American brands to Russian Elsup.

Chinese Berton Electronics, which claims to be “an agent of electronic components of well-known brands,” sold Western-branded chips to Russian Modern Digital Technologies.

In their turn, Russian companies Elsup, Modern Digital Technologies, Imotek, and other chip traders resold imported circuits to Ruselectronics holding.

The following chart provides a glimpse into the scale of the Chinese distribution network of Western chips.

The data provides insights into the link in the chain that gets U.S. chips into Russia despite export bans. In this chain, Chinese suppliers resell the chips to Russian buyers that then supply them to the Russian defense industry.

How many times chips are sold and resold before ending up in a Russian defense company is anyone’s guess.

According to customs records, American chips are produced in different countries, including the U.S., China, Taiwan, Malaysia, the Philippines, and others. In other words, some of these chips were most likely manufactured in American factories located outside the U.S.

“The key Western producers have several production facilities in countries like China, Vietnam, the Philippines, Malaysia, and a few in Thailand and Taiwan. Some of these are Chinese factories working on license, while others are daughter companies,” says Erlend B Bjortvedt, founder of Corisk, an Oslo-based consulting company that explores sanctions and sanction evasion.

Bjortvedt adds that “this does not reduce their liabilities to follow sanctions”. “This liability includes daughter companies and U.S. and EU citizens in the management or board of daughter companies abroad,” he explains.

How can the flow of Western chips into Russia be stopped?

Further sanctions on foreign companies that help Russia obtain scarce weapons components, as well as increased compliance by Western manufacturers, are two key steps to reduce such supplies, experts say.

“When a product that is prohibited for sale to Russia, according to U.S. rules, goes from China to Russia, this is not a violation from China’s perspective. However, it would be a violation of sanctions from the U.S. point of view,” explains Vladyslav Vlasiuk, Ukraine’s presidential commissioner for sanctions policy.

“That’s why Chinese companies that supply microelectronics to Russia appear on U.S. sanctions lists,” Vlasiuk explains.

It is noteworthy that half of the Chinese chip suppliers to Ruselectronics holding identified by the Kyiv Independent, as well as their Russian buyers, are not yet under U.S. sanctions. That is, their activities have not yet been noticed by the authorized U.S. sanctions authorities.

The Kyiv Independent reached out to dozens of Chinese companies mentioned in this article for comments, but did not receive any replies by the time of publication.

James Byrne of RUSI spoke to the Kyiv Independent about his experience of communicating with chip manufacturers. According to him, they complain that they have limited visibility, meaning they can only see “one or two steps down with the chain.”

“If you’re Texas Instruments or Intel, you have large distributors. The distributors sell components to all sorts of entities all over the world. Let’s say you sell to some distributor in Hong Kong, and then they sell to another entity in Hong Kong, and that entity ships them to the Russians. I think it’s a difficult problem to solve, but it doesn’t mean it’s impossible.”

The Kyiv Independent contacted all the Western chipmakers mentioned in the article. Those who responded called the resale of their chips to Russia illicit and unauthorized, condemning it.

Large manufacturers can tighten control over who they sell banned goods to and refuse risky customers, some of the experts say.

“Western chips manufacturers have had tremendous growth and profits over the last decades, but they have not invested in compliance and internal investigation,” says Erlend B Bjortvedt, who works closely with customs data analysis at Corisk.

“One company I researched had 60,000 employees but did not see big and obvious red flags in their value chain,” he says.

“The loopholes in the digital components industry can be closed by forcing producers to invest in internal control resources through preventive investigations with strong penalties, and by deterring third parties through forceful secondary sanctions of foreign banks,” according to Bjortvedt.

Until that happens, American and European components make it possible to produce new batches of Russian weapons that attack Ukrainian cities and kill civilians.

Note from the author

Hi, this is Alisa Yurchenko, the author of this story.

I’m writing this note shortly after reading the news that the U.S. President Donald Trump ordered a suspension of military aid to Ukraine — a move that will manifest, among other things, that Ukraine might not have the way to protect itself from the Russian missiles. It adds to the bitterness of this moment is the understanding that Russian missiles that have been hitting Ukraine in the past three years would not have been produced if it wasn’t for the Western chips and other components.

Stories like this can create the wrong impression that export restrictions on critical components to Russia have failed. But they did have some effect. The need for workarounds made the chips 40 percent more expensive for Russian importers. We see it in the leaked emails dating back to the first months of Russia’s full-scale invasion of Ukraine. Another, even more important result is a reduction in Russian imports of digital components and chips after December 2022, according to sanctions analysts. The trade through intermediaries has slowed down, they say. This gives us hope that if the pressure on Western chip sales through China, Hong Kong and other third countries is increased, Russia will not be able to produce missiles and other weapons.

How does logic work? Decoders and Demultiplexers

Greetings to all the fans of microcontrollers and digital chips! Today, we will get acquainted with decoders and demultiplexers that allow one to expand microcontroller ports, transfer a lot of data over a few wires, create stunning lighting effects, and much more.

In the post about the CD4017 decimal counter-decoder, we've put together the running fire effect. The chip counted from zero to nine and lit the corresponding LED, which created a nice, dynamic image.

The picture becomes even better, more dynamic, and more varied if you take two CD4017s: one lighting the LEDs horizontally and the other vertically.

Today's scheme of ring running lights is different from the previous one, firstly, as the CD4017 is clocked not by the NE555 timer but by a symmetrical transistor multivibrator.

The multivibrator consists of two stages with a common emitter on transistors Q1 and Q2. These two stages are exactly the same, making the multivibrator symmetrical.

The input of each stage is connected to the output of the other through an electrolytic capacitor.

A capacitor stores electrical charge. The voltage between the plates of a capacitor is proportional to the charge (in coulombs) it has accumulated.

The larger the capacity, the more charge the capacitor needs to accumulate for the voltage across it to increase by one volt. For example, 1 microfarad means that charging a capacitor at 1 volt requires 1 microcoulomb of electricity.

Resistors limit the current. The current through a resistor equals the voltage divided by the resistance. For example, at a voltage of 1 volt, a current of 1 milliamp flows through a resistor with a resistance of 1 kilohm.

Current refers to the amount of electricity passing through a conductor, resistor, or anything else per unit of time. One milliamp is equal to one millicoulomb per second.

So, a capacitor with a capacity of 1 microfarad will charge or discharge 1 volt with a current of 1 milliamp in one millisecond. And a current of 1 milliamp will flow through a resistor with a resistance of 1 kilohm if the voltage across the resistor is 1 volt.

You can see where I'm going with this: capacitors and resistors can set the time and, accordingly, the frequency of oscillations if we have a threshold element that switches at a certain voltage value.

In our multivibrator, the role of these elements is played by transistors. For the bipolar transistor to open, current must flow through the base. And for current to flow, the voltage between the base and emitter must reach the direct drop level at the p-n junction.

Now, let's see how we have the LEDs hooked up. Each of the ten channels is designed the same way. To avoid unnecessary clutter, the diagram shows just one.

When the voltage level at the Q0 output of the CD4017 chip is high, the electrolytic capacitor C3 is quickly charged through the diode D1 to a voltage just below the voltage of the power supply. Transistor Q3 opens, and LED1 and LED2 get lit.

At the start, Q3 is in saturation mode, and the current through the LEDs is determined by the resistance of resistor R6; the voltage across it is equal to the supply voltage minus the sum of the LEDs' operating voltage and the transistor's UCE.

When the next clock pulse arrives from the multivibrator, the logical one moves to the following output of the CD4017 microcircuit. Subsequently, a logical zero appears at its output Q0. Still, capacitor C3 can't discharge through diode D1 because the diode does not conduct current in the opposite direction.

However, C3 is gradually discharged through resistor R7 by the base current Q3. This current is equal to the difference in voltage across C3 and Ube of transistor Q3 divided by the resistance R7.

As capacitor C3 discharges, the voltage across it decreases gradually, and the base current decreases accordingly. As soon as the product of the base current and the transistor current gain h21e becomes lower than the current through resistance R7, the collector current, also known as the LED current, will begin to decrease.

Thus, each LED flashes brightly and then dims down to zero when C3 discharges to voltage Ube and the transistor turns off.

Depending on the clock frequency, tuned by variable resistor R4, the LED will go out completely or continue to glow dimly until a complete counting cycle has passed, and the circuit that lights this LED has again reached a logical one.

In the video example, I've been using different color LEDs, which glowed with varying brightness levels and went out at different speeds.

The following circuit does almost the same thing but with a few quirks.

First, instead of the decimal CD4017 counter, I used binary CD4060. It is already familiar to us since I devoted a separate post.

The CD4060 has a built-in clock generator, which requires only one capacitor and two resistors to operate. Therefore, this circuit does not need a transistor multivibrator or NE555.

To get running lights, we need a decoder that, at b000 at the input, will light the zero LED, at b001—the first, at b010—the second, and so on, up to the seventh LED at 111.

The 74HC138 chip, a 3:8 binary decoder-demultiplexer, executes this function in our circuit.

Each of the 3-input AND gates processes possible combinations from 000 to 111. To handle logic zeros, inputs have inverters.

The outputs of the microcircuit are also connected through inverters. So, unlike the CD4017, where a logic one moves between ten outputs, the 74HC138 will have a low level at the output, corresponding to the input value, and the other seven outputs will be high.

Or all eight outputs could be high if the decoder is disabled. For the decoder to work, inputs ¬G0 and ¬G1 must have logic zeros, and G2 must have one.

From the counter outputs Q7, Q8, and Q9, numbers from b000 to b111 are supplied to the decoder data inputs A0, A1, and A2. And the signal from Q10 is supplied to the control input E3.

It turns out that the LED lighting cycles will alternate with empty cycles when pulses are not supplied to the LED control units, and the brightness gradually decreases.

Please note that here, we have the chip facing the diode's cathode and not the anode. Transistors use PNP structures, which are opened with a negative signal, rather than NPN, which is opened with a positive one.

The electrolytic capacitor here is charged by the base current of the transistor and discharged through the diode and the chip's output. As you can see, this upside-down scheme also works.

The program memory controller in our homemade processor unit was the 4:16 74HC154 decoder-demultiplexer. It differs from the 74HC138 in one additional input bit. This doubles the number of outputs!

Multiplexers can be cascaded. Two 74HC154s will make a 5:32 decoder. This would take four 74HC138 chips to perform the same function.

The three least significant bits, N0, N1, and N2, are equally supplied to the inputs of both decoders. And the most significant bit turns off the first decoder and turns on the second.

This means that values from b0000 to b0111 are handled by eight corresponding outputs of the first chip, and from b1000 to b1111, the second one comes in with its eight lines.

Those simple means help us perform different tasks provided by trusty logic chips.

Technique simultaneously locates multiple defects on microchip circuits

Defective computer chips are the bane of the semiconductor industry. Even a seemingly minor flaw in a chip packed with billions of electrical connections might cause a critical operation in a computer or other sensitive electronic device to fail.

By modifying an existing technique for identifying defects, researchers at the National Institute of Standards and Technology (NIST) have developed a method that can simultaneously locate individual electrical flaws in multiple microcircuits on the same chip. Because the technique relies on a relatively inexpensive and common imaging tool, an atomic force microscope (AFM), it may provide a new way to test the interconnected wiring of computer chips in the factory.

An AFM features an ultrasharp tip attached to a tiny cantilever that vibrates like a diving board. In the standard mode of operation, scientists apply an AC (alternating current) voltage to the tip as it scans across individual wires buried in parallel several micrometers (millionths of a meter) below the surface of a silicon chip. The voltage difference between the tip and each wire generates an electric force revealed as changes in the frequency or amplitude (height) of the vibrating tip. A break or defect in a wire will show up as an abrupt change in the vibration of the tip.

Everything you should know about Electrical Engineering

Electrical engineering is an associate engineering discipline involved with the study, style, and application of kit, devices, and systems that use electricity, physics, and electromagnetism. It emerged as a recognizable associate occupation within the latter 1/2 the nineteenth century when commercialization of the electrical telegraph, the phone, and power generation, distribution, and use.

Electrical engineering is currently divided into a good vary of fields together with laptop engineering, power engineering, telecommunications, radio-frequency engineering, signal process, instrumentation, and physics. Several of those disciplines overlap with alternative engineering branches, spanning a large variety of specializations together with hardware engineering, power physics, physics and waves, microwave engineering, engineering science, chemical science, renewable energies, mechatronics, and electrical materials science. See the gloss of electrical and physics engineering.

Electrical engineers generally hold a degree in engineering science or electronic engineering. Practicing engineers could have skilled certification and be members of a knowledgeable body or a global standards organization. There are various electrical engineering jobs as well. These embody the International Electrotechnical Commission (IEC), the Institute of Electrical and physics Engineers (IEEE), and therefore, the establishment of Engineering and Technology (IET) (formerly the IEE). The IEC prepares international standards for engineering science, developed through accord, because of the work of twenty,000 electrotechnical specialists, returning from 172 countries worldwide.

Electrical engineers add an extensive selection of industries, and therefore, the skills needed area unit likewise variable. These vary from circuit theory to the management skills of a project manager. The tools and instrumentality that a personal engineer might have area unit equally variable, starting from an easy meter to a high finish analyzer to stylish style and producing computer code.

Subfields

Electrical engineering has several subdisciplines, the foremost common of that area unit listed below. Though there area unit electrical engineers WHO focus entirely on one in all these subdisciplines, several manage a mix of them. Typically bound fields, like electronic engineering and laptop engineering, area unit thought of separate disciplines in their title.

Power

Power deals with the generation, transmission, and distribution of electricity because of a variety of connected devices. These embody transformers, electrical generators, electrical motors, high voltage engineering, and power physics. In several regions of the globe, governments maintain an associate electrical network known as an influence grid that connects a spread of generators beside users of their energy. The users purchase electricity from the grid, avoiding the pricey exercise of getting to come up with their own. Power engineers may go on the look and maintenance of the facility grid still because of the power systems that connect with it. Power engineers may additionally work on systems that don't connect with the network, known as off-grid power systems, that, in some cases, area unit preferred to on-grid systems. The longer-term includes Satellite controlled power systems, with feedback in real-time to stop power surges and forestall blackouts.

Control

It focuses on the modeling of various vary of dynamic systems and, therefore, the style of controllers, which will cause these systems to behave within the desired manner.[74] To implement such controllers, electrical engineers could use electronic circuits, digital signal processors, microcontrollers, and programmable logic controllers (PLCs). Management engineering contains a wide selection of applications from the flight and propulsion systems of business airliners to the controller gift in several trendy cars.[75] It conjointly plays a vital role in industrial automation.

Control engineers usually utilize feedback once planning management systems. For instance, in an associate automobile with the controller, the vehicle's speed is unceasingly monitored and fed back to the system that adjusts the motor's power output consequently. Wherever there's regular feedback, management theory may be wont to confirm; however, the system responds to such feedback.

Electronics

Electronic engineering involves the look and testing of electronic circuits that use the properties of parts like resistors, capacitors, inductors, diodes, and transistors to attain specific practicality. The tuned circuit that permits the user of a radio to separate virtually one station is simply one example of such a course. Another instance of the analysis could be a gas signal conditioner.

Before the Second War, the topic was usually referred to as radio engineering and primarily was restricted to aspects of communications and measuring instruments, business radio, and new tv. Later, in post-war years, as shopper devices began to be developed, the sphere grew to incorporate trendy tv, audio systems, computers, and microprocessors. Within the mid-to-late Nineteen Fifties, the term radio engineering step by step gave thanks to the name electronic engineering.

Before the invention of the microcircuit in 1959,  electronic circuits were created from distinct parts that might be manipulated by humans. These discrete circuits consumed a lot of houses and power and were restricted in speed, though they're still prevalent in some applications. In contrast, integrated circuits packed an oversized number—often millions—of little electrical parts, chiefly transistors, into a bit of chip around the size of a coin. This allowed for the powerful computers and alternative electronic devices we tend to see nowadays.

Tools and Work

From the worldwide Positioning System to power generation, electrical engineers have contributed to the event of a good vary of technologies. The style, develop, test, and supervise the preparation of electrical systems and electronic devices. For instance, they'll work on the look of telecommunication systems, the operation of electrical power stations, the lighting and wiring of buildings, the look of house appliances, or the electrical management of commercial machinery.

Satellite communications is on which electrical engineers work on. Being fundamental to the discipline area unit, the sciences of physics and arithmetic as these facilitate to get each a qualitative and quantitative description of; however, such systems can work. Nowadays, most engineering work involves the utilization of computers, and it's a commonplace to use software programs once planning electrical systems. Still, the flexibility to sketch concepts continues to be valuable for quickly human activity with others.

Although most electrical engineers can perceive basic circuit theory (that is that the interactions of parts like resistors, capacitors, diodes, transistors, and inductors during a circuit), the methods utilized by engineers usually rely on the work they are doing. For instance, quantum physics associated solid-state physics may well be relevant to an engineer engaged on VLSI (the style of integrated circuits), however area unit mostly moot to engineers operating with macroscopical electrical systems. Even circuit theory is not relevant to someone planning telecommunication systems that use ready-to-wear parts. Maybe the foremost necessary technical skills for electrical engineers area unit mirrored in university programs that emphasize strong numerical skills, laptop accomplishment, and, therefore, the ability to know the technical language and ideas that relate to engineering science.

Electrical engineers employ a wide variety of instrumentation. For straightforward management circuits and alarms, a basic multimeter measure voltage, current, and resistance could satisfy. Wherever time-varying signals have to be compelled to be studied, the electronic equipment is additionally associate omnipresent instrument. In engineering and high-frequency telecommunications, spectrum analyzers, and network analyzers area unit used. In some disciplines, safety may be a specific concern with instrumentation. For example, medical physics designers should take into consideration that a lot of lower voltages than traditional may be dangerous once the electrodes area unit directly to bear with internal body fluids. Power transmission engineering conjointly has excellent safety issues thanks to the high voltages used; though voltmeters could, in theory, be like their low voltage equivalents, safety and standardization problems build them different. Several disciplines of engineering science use tests specific to their training. Audio physics engineers use audio to take a look at sets consisting of a symbol generator and a meter, mainly to live level; however, conjointly alternative parameters like harmonic distortion and noise. Likewise, info technology has its own take a look at sets, usually specific to specific information, and therefore the same is true of tv broadcasting.

For many engineers, technical work accounts for under a fraction of the work they are doing. Plenty of your time may additionally be spent on tasks such as discussing proposals with shoppers, getting ready budgets, and determinant project schedules. Several senior engineers manage a team of technicians or alternative engineers and for this reason project management skills area unit necessary. Most engineering comes to involve some documentation and robust communication skills area unit, thus vital.

The workplaces of engineers area unit even as varied because of the sorts of work they are doing. Electrical engineers could also be found within the pristine science lab surroundings of a fabrication plant, onboard a military ship, the offices of a house, or on the website at a mine. Throughout their operating life, electrical engineers could realize themselves oversight a good vary of people together with scientists, electricians, laptop programmers, and alternative engineers.

Electrical engineering has associated an intimate relationship with the physical sciences. For example, the man of science Lord Kelvin vies a significant role within the engineering of the primary transatlantic telegraph cable. Conversely, the engineer physicist made significant work on the arithmetic of transmission on telegraph cables.Electrical engineers area unit usually needed on primary science comes. for example, massive particle accelerators like CERN want electrical engineers to manage several aspects of the project.

5 Killer Quora Answers on 해외선물사이트

21st Century Casinos

Casinos are very popular during the 21st century. They are a place where players compete against bankers or the house and the goal of casinos is to keep players in the casino for longer than necessary. The casinos around the world share an the exact same characteristics. European countries began changing their laws at the end of the 20th century to permit gambling. The United Kingdom, for example has had licensed gaming clubs since. The only difference is that membership is required. France legalized casinos in 1933, and boasts one of the most renowned European gambling halls.

In the United States, the percentage of Americans who played at casinos was up from 24% in 1989 to 24% by the year 2008. These figures are greater than those of other nations. In 1988, just 25% of Americans had at least an associate's degree. 26% had a graduate degree. But, a majority 해외선물 of them were not in college at all. The contrast between these two years is striking. The amount of Americans who went to a casino isn't increasing, but the trend has remained constant.

Casinos have increased their use of technology because of the increasing popularity of gambling. To monitor their games, casinos often use video cameras as well as computers. Another method casinos use to ensure fair play is through "chip tracking." These chips contain embedded microcircuits, so that casinos can monitor their patrons' wagers every minute. Routinely, the roulette wheels are checked for statistical deviations. The games that are enclosed allow players to place their bets using buttons while surveillance officers can observe them from above.

Despite their uncertain reputation, casinos have made profits by providing more games than they could afford to pay for. These casinos offer high odds of winning and are willing to accept any bet within their budget. Therefore, they never lose money when playing games. Casinos never run out of cash, as an example. To entice big bettors casinos often offer extravagant incentives, including discounted transportation or cigarettes for free. However, the main reason behind the casinos' popularity lies in their willingness to reward huge gamblers with incentives like these.

Technology is among the best methods to monitor the casino's operations. To keep track of the casino's activities Casinos have computers and video cameras. For example, the casino utilizes "chip tracking" to keep track of bets on roulette wheels. Apart from that, the casino offers customers other types of incentives. It is possible to receive free drinks, cigarettes, or discounts on other products. This is the most popular method for casinos to make players spend more.

The casino's décor is a reflection of the business. The floor of the casino is usually vibrantly colored, while the walls are adorned with bold patterns that are colorful and vibrant. The colors are bright and exciting, and the casino staff are trying to make it easier for patrons to spend money. You can also find many options for food, drinks and entertainment. Casinos are a place where gamblers lose track of time. So, what are the elements that make casinos so famous?

The decor of the casino is not only attractive, but it is as well secure. Casinos boast among the most secure environments around the globe. They don't have any clocks, but they do have one-way glass in the ceiling that allows surveillance staff to watch the floor of the casino. This is why lots of money disappears every day in a casino. Casinos aren't able to pay these expenses and are more likely to squander the cash.

Security features are essential to the casino. If there is security personnel and security personnel, it's hard to determine who is watching over the security of the patrons. Some casinos even have catwalks on the ceilingthat allow security personnel to observe at the floor of the casino. During the day, staff will monitor the casino floor for suspicious activity. If someone is trying to steal money, they are unlikely to be able to prove they have the proper identity.

Security at the casino is of great concern to casino patrons. Security personnel are on the eye on the floor and patrons. Some casinos even have a catwalk built into the ceiling that is above the floors, allowing surveillance personnel to watch directly at the casino floor. The glass is single-way, therefore, people cannot cheat. However, casinos' security systems aren't perfect. Casinos cannot have a timer. This would pose a serious risk to the fire.

How does logic work? CD4060 Binary CounterHow does logic work? CD4060 Binary Counter

In the previous post (How does binary logic work? Shift registers), we controlled the CD40194 shift register modes by applying logical ones and zeros, high and low voltage levels, to its two control inputs, S1 and S0.

To do this, we assembled a simple circuit of two synchronous JK flip-flops on the CD4027 chip, which sequentially divides the frequency in half. In other words, it counts pulses in the binary number system.

What is a JK trigger, you may ask? We are familiar with the D flip-flop. It is synchronous; it reads the input state and saves it as the output state at the edge of the clock pulse.

And the RS flip-flop is asynchronous: a one at the reset input sets its output to zero, and a one at the specified input sets its output to one. When both inputs are zero, the output state does not change.

The JK flip-flop is synchronous and is similar to the RS flip-flop. It reacts to the input states only at the edge of the clock pulse. A high level at input J sets the flip-flop output to one, at input K to zero. At both inputs, J and K, it reverses the trigger state, dividing the clock frequency in half. And if the logic levels at both inputs are low, then the output state does not change.

Each press of the button switches the circuit from the previous state to the next one: 00 → 01 → 10 → 11 → 00, and so on.

So, the resulting circuit counts pulses! If one converts binary numbers to the decimal system, one gets 0 → 1 → 2 → 3 → 0...

If we'd like to count from 0 (000) to 7 (111), we'll need a third flip-flop; to count from 0 (0000) to 15 (1111), four flip-flops will be required, and so on. One flip-flop corresponds to one binary digit.

Our circuit has four familiar D flip-flops of two CD4013 microchips forming a four-bit binary counter.

This counter is clocked not by pressing a button but by a pulse generator on the NE555 integrated timer.

Our third example will be two music boxes with lighting effects assembled according to the same circuit diagram. See how interesting this is! The algorithm for switching lights is the same. Still, you can take LEDs of different colors, place them in different ways, and get completely different effects!

The CD4060 binary counter chip is used here. The basis of its internal structure is a chain of 14 flip-flops forming a 14-bit counter. Pin outputs of the chip are not available for all the digits, only from the fourth to the tenth and from the twelfth to the fourteenth.

So, the CD4060 chip allows one to divide the frequency into 16, 32, 64, 128, 256, 512, 1024, 4096, 8192, and 16384. Huge numbers, right?

The CD4060 can be clocked from an external source via pin 11. But the chip also has a built-in clock generator. To enable it, just connect a capacitor and two resistors to pins 9, 10, and 11. This is exactly what is done in our diagram.

The oscillation period of the clock generator is set by a stage of capacitor C1, series-connected resistor R1, and potentiometer R3, allowing one to adjust the clock frequency and, subsequently, the speed of changing the lights.

The bases of transistors are connected to the outputs corresponding to frequency division by 32, 64, and 128, and these transistors toggle groups of LEDs. But should we connect the transistor's base directly to the microcircuit's logical output without a series resistor?

You should definitely avoid it if the transistor is connected to a circuit with a common emitter. Here, we have PNP transistors S9012 with the emitter circuit load. That means we have a circuit with a common collector. Such a circuit does not need a resistor to limit the base current of the transistor.

The LED groups will light up with a logical zero at the base of the transistor and turn off with a logical one.

The sequence of logical levels and lighting up groups of LEDs, numbered according to transistors Q1-Q3, is as follows: 000 → 001 → 010 → 011 → 100 → 101 → 110 → 000 321 → 32 → 31 → 3 → 21 → 2 → 1 → 321

Case 111, when none of the LEDs light up, is impossible in this circuit. More precisely, it happens so briefly that it's hard to notice.

Diodes D1–D3 and resistor R4 together form an OR logic element. As long as at least one of the outputs Q5, Q6, or Q7 is logic low, the reset input of the CD4060 chip is pulled to ground through one or more diodes.

As soon as the counter reaches logic ones on all three outputs we use, the diodes stop shunting the reset input, a high logic level appears on it, and the microcircuit resets all its flip-flops to a low level.

Then, a logical zero appears again at the reset input, and the counter restarts again.

We could've saved three diodes and a resistor by simply connecting Q8 to the reset input. Or just never use the reset input at all and let the counter tick from 0 to 32767 and then from zero again.

But then, after the sequence reaches phase 110 with just the group of LEDs connected to transistor Q1 lit, all the LEDs will go out until the counter reaches 1000, and if a reset occurs.

Our magic musical lantern won't be so beautiful working in such a way. Therefore, the developers added a 3OR gate with a resistor and three diodes.

The BJ1552 is a digital music chip in a transistor package, referred to as just a transistor in the diagram for simplicity's sake. A melody is saved in memory and played whenever the chip is powered on.

Transistor Q5, which serves as an audio amplifier, unlike Q1-Q3, is an NPN-type connected in a common-emitter circuit. A resistor is needed here to limit the base current, and it is built into the BJ1552 chip.

We have already encountered the CD4060 when assembling an electronic clock with a digital display. That circuit used the CD4060's ability to operate with a crystal frequency regulator.

In this case, a clock quartz is used; its resonant frequency is 32768 hertz, 2 to the 15th power. One needs to divide this frequency in half 15 times to get one pulse per second.

The CD4060 bifurcates the frequency only 14 times, so we needed an additional synchronous D-trigger U12A of the CD4013 chip for the fifteenth frequency division.

The SN74HC161N chip, on which the registers of our homemade microprocessor are built, is also a counter. But unlike the CD4060, it's only 4-bit, not 14.

But SN74HC161N is not just a counter but a synchronous latch register with a counter feature. Or, in other words, a counter with the ability to input the desired value.

If we wanted to write a value to the CD4060, we would need to reset it and apply the number of clock pulses equal to the value we want to write to the counter. And the SN74HC161N supports synchronous parallel writing over four wires.

Another thing is that the SN74HC161N has no built-in clock generator, so we've made a clock generator on two inverting Schmitt triggers of the SN74HC14N chip.

This generator is designed in the same way as the one built into the CD4060, and in the same way, it requires a timing capacitor and two resistors.

As you can see, there are many different digital chips, each with a unique set of useful functions. We can choose those chips that are best suited for our task. And if some function is missing, you can always find a way to implement it.

Single-Electrode Material Streamlines Functions into a Tiny Chip

This illustration portrays on-chip electrochemical energy storage incorporated with thin-film electronic devices at the transistor level utilizing a single-electrode material for all devices.Reproduced with approval from referral one © 2019 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim

The capability to integrate numerous functions into a single microchip is a substantial advance in the mission to best the tiny, self-powered sensing units that will broaden the Web of things. KAUST scientists have actually handled to integrate noticing, energy-harvesting, current-rectifying and energy-storage functions into a single microchip.

“Previously, researchers had to use bulky rectifiers that converted intermittent harvested electrical energy into steady direct current for storage in electrochemical microsupercapacitors,” states Mrinal K. Hota, research study researcher at KAUST and lead author of the research study.

Hota describes that the secret to incorporating whatever into a single chip was the advancement of ruthenium oxide (RuO2) as the typical electrode material linking all gadgets in the microcircuits. The group imagines a broad series of applications from keeping track of individual health signs straight from the body to ecological and commercial noticing.

“Our achievement simplifies device fabrication and realizes significant miniaturization of self-powered sensor devices,” states job leader Husam Alshareef.

A thin-film chip with the energy-storing microsupercapacitors arrayed along leading and bottom of the chip.

The ruthenium-oxide contacts are laid onto a glass or silicon substrate to link noticing, energy-harvesting and current-rectifying electronic devices with several electrochemical microsupercapacitors that keep the electrical energy. This develops a tiny system that can run with no battery power. Rather it utilizes readily available body language or equipment vibrations as the trustworthy and consistent source of energy.

“Unlike a battery, electrochemical microsupercapacitors can last for hundreds of thousands of cycles rather than just a few thousand,” Hota mentions. They can likewise provide a substantially greater power output from a offered volume.

A crucial to developing electrode material ideal for linking all gadgets was to make optimum ruthenium-dioxide surface areas with regulated roughness, problems and conductivity. These functions made it possible for the group to utilize RuO2 for both electronic devices and electrochemical microsupercapacitors.

A schematic illustration of the incorporated circuit made on a one-inch glass substrate. The chip integrates electronic devices and on-chip energy-storage systems.

Another important development was to utilize a gel that, after application, strengthens into the supercapacitors’ electrolyte. This is a material that transfers electrical charge in the type of ions. The strengthened gel was selected to prevent any damage to rectifiers and thin-film transistors.

The scientists now prepare to work to enhance the RuO2 electrodes even more and check out connecting several kinds of sensing units into their chips.  They likewise wish to examine including cordless interaction into the gadget. This would enable biosensors and ecological sensing units to send out information from another location to any cordless receivers, consisting of cellphones and desktop computers.

The group, led by Prof. Husam Alshareef, likewise consists of KAUST’s Prof. Khaled Salama and Prof. Z.L. Wang from the Georgia Institute of Technology in Atlanta, U.S.A..

What is the distinction between chips, semiconductors, as well as integrated circuits?

1. What is a chip? Chip is likewise called microcircuit, microchip, incorporated circuit (integrated circuit, IC), refers to the silicon wafer consisting of integrated circuits, tiny size, often part of a computer or various other digital devices. Chip is the cumulative name of semiconductor part products and also is the carrier of incorporated circuits separated by wafers. A Silicon wafer is a tiny piece of silicon-containing integrated circuits; it belongs to a computer system or various other electronic tools. 2. What is a semiconductor? Semiconductor refers to the conductivity of the conductor (conductor) and insulator (insulator) product at space temperature level, as the diode is a semiconductor device. Semiconductor describes a product whose conductivity can be managed and also can range from insulator to conductor. The importance of semiconductors is huge, both from the point of view of technology as well as economic advancement. A lot of today's electronic products, such as computer systems, cellular phone, or electronic recorders in the core system, have a close relationship with the semiconductor. Typical semiconductor materials consist of silicon, germanium, gallium arsenide, etc, and also silicon is one of the most influential one amongst all kinds of semiconductor products in business applications. Issue exists in various kinds, strong, fluid, gas, plasma, etc. We typically refer to materials with inadequate electric conductivity, such as coal, man-made crystals, amber, ceramics, and so on, as insulators. As well as the metals with better conductivity, such as gold, silver, copper, iron, tin, aluminum, etc, are called conductors. It can be merely in between the conductor as well as insulator materials called semiconductors. 3. What is an integrated circuit? An integrated circuit is a little electronic gadget or component. Making use of a certain process, a course requires transistors, resistors, capacitors and inductors, and also various other information as well as electrical wiring adjoined with each other, made in a small or several little semiconductor wafer or dielectric substrate, and after that packaged in a shell, become a microstructure with the called for circuit function; where all components in the structure have been made up of a whole so that digital parts in the direction of the miniaturization, reduced power intake, intelligence and It is a huge action towards miniaturization, low power intake, illumination, and high reliability. It is stood for by the letters "IC" in the circuit. The developers of the incorporated circuit were Jack Kilby (incorporated circuits based upon germanium (Ge)) and also Robert Noyes (incorporated circuits based on silicon (Si)). The majority of applications in the semiconductor industry today are silicon-based integrated circuits The incorporated circuit is a new semiconductor device established in the late 1950s and also 1960s. It is after oxidation, lithography, diffusion, epitaxy, dissipation of light weight aluminum, as well as various other semiconductor manufacturing procedures, the structure of a details feature of the circuit needed for the semiconductor, resistance, capacitance, and other elements as well as their link in between the cords are incorporated right into a tiny item of a silicon wafer, and afterwards welded plan in a tube covering of electronic gadgets. The product packaging shell has a variety of types, such as round shell, level, or double inline. Integrated circuit innovation includes chip manufacturing as well as design innovation, mainly in handling equipment, product packaging as well as screening, mass production, and style technology abilities. 4. What is the difference between a chip and also an IC? The emphasis to be expressed is various. Chip is a chip, normally referring to your nude eye can see a great deal of little feet or feet that can not be seen, yet an undeniable square item of that point. Nevertheless, the chip also includes a variety of chips, such as the baseband, voltage conversion, etc. The cpu stresses function, describing the system that does handling, which can be described as MCU, CPU, etc. Integrated circuits are a lot wider in range. The assimilation of some resistors, capacitors, and diodes together is considered an incorporated circuit, which might be an analog signal conversion chip or a logic control chip. Still, in general, the concept is a lot more in the direction of the bottom of things. The integrated circuit is composed of active gadgets, easy components, and also their affiliations made with each other on a semiconductor substratum or protecting substratum, developing structurally snugly linked, inside associated instances of electronic circuits. It can be split into three major branches: semiconductor integrated circuits, membrane circuits, and also hybrid integrated circuits. Chip is the collective name of semiconductor component items and also is the provider of integrated circuits separated by wafers. 5. What is the partnership and difference between semiconductor incorporated circuits and also semiconductor chips? Chip is short for an incorporated circuit; actually, the genuine definition of words piece refers to the integrated circuit package inside a bit of a big semiconductor chip, that is, television core. Strictly speaking, chips as well as incorporated circuits are not interchangeable. The incorporated circuit is manufactured by semiconductor innovation, thin-film modern technology, as well as thick-film technology. A details function of the circuit miniaturized in the form of a specific bundle of circuits can be called incorporated circuits. A semiconductor is a substance between an excellent conductor and also a non-good conductor (or insulator). Semiconductor integrated circuits include semiconductor chips as well as outer related circuits. 6. Semiconductor incorporated circuits. Semiconductor integrated circuits are energetic parts such as transistors, diodes, and so on, as well as passive parts such as resistors as well as capacitors, "integrated" on a single semiconductor chip according to a certain circuit affiliation to do a details circuit or system function. A semiconductor chip is a semiconductor device that is engraved and wired on a semiconductor sheet to achieve a specific placement. Not just silicon chips but shared likewise consist of gallium arsenide (gallium arsenide is harmful, so some low quality motherboard do not curious to decompose it), germanium, and various other semiconductor materials. Semiconductors additionally have patterns like cars. In the 1970s, Intel and also various other U.S. business in the vibrant random access memory (D-RAM) market dominated. Yet because of the appearance of huge computers as well as the need for high-performance D-RAM in the 1980s, Japanese firms topped the list. 7. Chip failing analysis The research laboratory introduces the capacity to carry out screening job based upon global, domestic, and also sector criteria, perform thorough screening job from the underlying chip to the actual product, from physical to logical, as well as provide security screening solutions for chip pre-processing, side-channel attacks, optical strikes, invasive strikes, ecological, voltage burr assaults, electro-magnetic shot, radiation shot, physical security, logical safety and security, performance, compatibility, and multi-point laser injection, etc. At the same time, we can carry out failing analysis as well as testing services that mimic the sensation of reproducing the failure of intelligent products and also learn the reason for failing, primarily including point pin workstation (Probe Terminal), responsive ion etching (RIE), micro-leakage detection system (EMMI), X-Ray discovery, defect reduced observation system (FIB system), etc.
