 MOSFETS as linear amps hi ho. Has any one here had any good experieance using MOSFETS in their linear region as a push-pull setup? I cannot find any PNP/NPN BJT that meet all my requirement but their are loads of MOSFETS that do. I would like to post some more info for a full discussion but this is for work and would be cheaky plus I have the MOSFET drive all sorted I am just after peoples views of using MOSFETS as linear push-pulls | |

| With some feedback, linearity should be as good as bipolar (Williamson circuit?).

Well its more of a voltage profile shaping cct for an IGBT drive and it needs to be very fast (~2000V/us) | ||

| What are you trying to do? If it is a linear amp, feedback is more effective in obtaining linearity.
