I have to make a pulse generator square wave for ultrasonic transducer with frequency 1 MHz and 70V for the amplitude, the input is function signal generator with 10V VPP output and 1 MHz. I have made it and it works, but there is a problem. There is always a ringing or overshoot in turn on or rise time but not for the fall. It happens for all frequency, not just in 1 MHz, in 100 KHz for an example, the overshoot is so tight or narrow. this is the circuit that i made
and this is the result of the output
what i have done 1. try to add resistor 1M or 10K in gate of MOSFET, the result : no output signal 2. Add Decoupling capacitor, the result : no effect
how i add up the resistor
So, how to fix the overshoot or the ringing of the output?
