Abstract :
A bias technique for low-voltage class AB amplifiers is presented. The approach exploits the bulk terminal to set the output quiescent current of a two-stage class-AB CMOS OTA in a reliable manner and without reducing the maximum swing capability. Simulations on a designed example using a 0.25-mum CMOS process show the viability of the approach.
