A bipolar rail-to-rail class-AB output stage that provides improved AC performance in low voltage applications. The bipolar output stage includes an input buffer stage, first and second complementary common emitter stages, and first and second control circuits biased and configured to assure class-AB operation of the first and second common emitter stages, respectively. The input of the bipolar output stage is applied to the input buffer stage, and the output of the bipolar output stage is provided by the second common emitter stage. The combination of the first common emitter stage and the first AB-control circuit operates as a current booster stage for the second common emitter stage, thereby obviating the need for a large power supply.
