class AB output stage

Hi,

I need to design a class AB output stage. It could be a source follower output stage or a common source output stage.. but the main criteria is class AB operation. I would really appreciate it if someone could post schematics of it including the biasing circuitry


Thank you

This is the best way:

May be this is helpful, too.

for the same subject, how do we do it for bipolar devices. the push - pull npn - pnp with a vbe bultiplier biasing the output voltage. .
