Abstract
A CMOS operational amplifier includes a biasing scheme for supplying current to a differential stage. A push-pull output stage includes a current sinking transistor which is coupled to a first output of the differential stage. A current mirror is coupled between a second output of the differential stage and the gate electrode of a current sourcing device in the output stage.
