I have the following circuit:
This is the data sheet for the MOSFET.
Using equations, I worked out that my Rgate should be 2.36 Ω. Rtest was a 470 Ω ceramic block resistor (due to it getting quite hot when turned on).
Connecting the oscillator, I see that I have this ringing effect on the square wave as shown here:
I am just wondering what the cause of this ringing effect is. Maybe you can provide a little detail on what it is and how to fix it. I increased the resistor value to 47 Ω which does lower the effect, but why?
Also, do you have any ideas on how I can calculate the power loss of the MOSFET?
