Abstract: An output power stage composed of a pair of transistors driven in phase opposition and wherein the pull-up transistor is a PNP bipolar transistor and the push-down transistor is an n-channel FET has an outstandingly improved power handling capability per semiconductor area occupied, coupled with a large output voltage swing, without requiring the use of externally connected discrete boot-strap components. The "hybrid" output stage is fully complementary and the current-driven, bipolar, pull-up transistor may be driven through an auxiliary stage composed of a field effect transistor for substantially eliminating output power requisites of a signal amplification stage.
