Abstract
A novel low-voltage class AB output stage integrated in BiCMOS technology is presented. It features a novel class AB low impedance output stage and has a simple but efficient quiescient current regulation. The amplifier exhibits a 3dB bandwidth of 5MHz while driving a combined parallel load of 30 /300pF at 2V power supply voltage. The voltage amplification of the output stage is greater than 1.0 which simplifies the design of the preceeding stage.
