MOS tube acceleration and deceleration switch circuit principle

How does the MOS acceleration and deceleration switch work?

Take NMOS as an example. When the current flowing into the gate is increased, the MOS will be accelerated when it is turned on. When the current flowing into the gate is reduced, the MOS will be decelerated when it is turned on; when the MOS tube needs to be turned off quickly, the gate charge needs to be released faster, and the deceleration shutdown will decelerate the release. PMOS is the reverse process of the above.

We understand the switching process of the MOS tube. When an NMOS is turned on, the gate is charged. When the Cgs charge is full, the gate will turn on the threshold. When the NMOS is turned off, the GS charge needs to be discharged. When the charge is discharged, the gate will turn off the threshold. This explains the fast switch and deceleration switch we talked about earlier.

So what is its fundamental mechanism? In essence, it is related to the gate resistance of the MOS tube. Because the gate resistance directly controls the size of the gate current, the switching speed varies with the gate resistance value. And choosing the right one is very important. Different gate resistors can be used for different switching speed requirements of MOSFET.

When the MOS tube is turned on, the gate resistors: R1 and R2 are connected in parallel, and R2 is closed when it is turned off, so that it can be turned on faster and turned off slower; or like this circuit, the MOS tube passes through the gate resistor R1 when it is turned on, and R1 and R2 are connected in parallel when it is turned off, so that it can be turned on slower and turned off faster.

The turning on and off of MOS is a dynamic process. The control end and the gate level are the same during continuous off or on, but the control end and the gate level are different at the moment of turning on and off. The gate level changes slower than the control end level, so the different levels will cause the gate current to flow into or out of the gate.

Increasing the gate resistance value will slow down the switching speed of the MOSFET and increase its switching loss. Reducing the gate resistance value will increase the switching speed of the MOSFET.

This has actually been mentioned in the previous section about the selection of the size of the resistor. It is not recommended to use K-level resistors when controlling the switching speed. Common resistance values ​​are 3.3Ω/10Ω/33Ω, etc. Some relatively large discharge currents can be achieved by selecting low output impedance MOSFETs or voltage devices, such as using accelerating diodes.

Technically Speaking.

Not that rare for me to roll my eyes when a reviewer or sales person tries to explain a technical thing and blows it.

Hey I am not an electrical engineer, but that was only one and a half years difference in my university education and I did hang with a few. For that I do know a MOSFET from a Bipolar and what a Farad is. I can solder. I know my limits and can see where other people exceed theirs.

I watched a you tube review by this stern person from TAS about a new (expensive) Technics Integrated Amplifier. He was quite a ways out of his depth and went on for some time explaining what he remembered about what someone told him.

The power end is a Class D amp. Everything seems to be now. Trick is about everything else is digital.

I wish he had just stayed in his lane and said how it sounded. Apparently very good. It is one box, handsome, not cheap by any means, but reachable. If I had a small place I would be happy with this a turntable and my invisible speakers. Yes it has a phono input.

He missed or ignored or failed to notice one very cool thing. All speakers have not flat impedance curves. One thing impedance can do is mess up the phase of signals in the Bass. Volts will peak before or after the current so depending on the type of amplifier it has one or another type of trouble. Phase is important low down as that is where you are most sensitive to it. Higher up you would never know. He does mention how good the Bass is.

What this thing can do is really cool. You can read about it on Technics website as I did. This amplifer can send a test signal to your speakers and calibrate their impedance. It then can adjust the phase of the signal to keep it coherent. The effect in the Bass is more accuracy and clearer. That can be done as it has internal DSP that lets the machine fiddle. Digital has its advantages.

There is another version of this thing that does not have an MC preamp and just a MM. That one is called the SU-G700. It is less expensive.

Both versions are economy versions of an ICON product. It seems when huge multi-billion dollar companies want to show off they really can. Little guys working in sheds in the Cotswolds cannot keep up stamp their feet as they may.

Of course that means there is a bigger one. Dear dear.

How a MOSFET Works – with animation! | Intermediate Electronics

In this tutorial, using some animation, Josh explains how a MOSFET works. These Metal Oxide Semiconductor Field Effect Transistors are strangely straightforward in their operation but the logical leap to create them, and the way they have changed the way the world works is amazing. While there are different types of Field Effect Transistors (FETs), the MOSFET is a great example of how a field…
