Abstract
A CMOS output stage with large voltage swing particularly suited for output buffers in monolithic analog subsystems has two, push-pull connected, complementary MOS transistors and has feedback for improving its swing and linearity characteristics in comparison with those of the output stages without feedback of the prior art and also has sufficient stability characteristics which are re-established by local compensation. Furthermore the quiescent current is stabilized by a dedicated control circuit cooperating with a local feedback circuit.
