Need an analog driver for a big mosfet. Not sure if there might be an appropriate power op-amp out there or not. Linearity is not too important as long as I can drive the mosfet to different pulse amplitudes. Seems that most mosfet drivers are digital. Right now I'm considering a wimpy op-amp driving a PNP/NPN pair. The mosfet itself would be a IRFZ44 or similar. I'd like to get a rise-time on the gate down to a few uS.
