Abstract
A new class AB output stage for CMOS op-amps, with accurate quiescent and minimum current control, is proposed. The proposed stage can be operated with a supply voltage close to the threshold voltage of the transistor. A dynamic biasing scheme allows it to operate over a wide range of supply voltages. Simulation results are provided that are in good agreement with expected values.Keywords
