MOSFET Driver circuit

But I’ve program CPLD to generate the frequency of 500KHz(for testing).

@naik

I am driving those MOSFET with the 2MHz sampling frequency,

Why are you simulating with 2MHz if your hardware is driving it at 500KHz?

@naik

90K resistor is fine

I know 90K is fine.

However, your simulation probably used ideal capacitors and you may need to change the actual caps to not use ceramic.

[naik]

Yes, I am going to change the type of those caps.
Simulation Circuit and Output:

I was just checking the frequency because the actual frequency is 500KHz but it is sampled at 2MHz. Yes, that shouldn’t make difference in the performance of the MOSFET.

Hey everyone,
My goal is to build pulser for ElectroMagnetic Acoustic Transducer with microsecond pulse duration and peak current >50 A. Do you know the solution with two MD1213 for inductive load in H bridge?
