Hello, I'm new to the analog design world and I have a probably dumb question.
I have a normally-on transistor that I want to shut off with a negative voltage. The issue is that I only have a positive supply voltage and so I thought that I can generate the negative voltage from GND by using a negative charge pump with a voltage regulator system.
Here comes the dumb question; can't I just invert the positive supply voltage using an inverting amplifier and fed it to my gate driver that controls the transistor? Does it have any drawbacks? Would it be bad for my transistor?
Thank you.
