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:
"Compact Low-Voltage Power-Efficient Operational Amplifier Cells for VLSI", by Klaas-Jan de Langen and Johann H. Huijsing, IEEE Journal of Solid-State Circuits, vol. 33, No. 10, Oct. 1998
