Abstract

An integrated circuit including an NPN transistor and a compound PNP transistor. The PNP transistor is of the form of a conventional vertical NPN transistor, in common base configuration, supplying base current to a lateral PNP transistor. The emitter of the vertical NPN is disposed in the emitter of the lateral PNP; the base and collector of the vertical NPN are the emitter and base regions, respectively, of the lateral PNP. The separate NPN transistor may be of conventional configuration, or may also be compound, with a lateral PNP supplying base current to an inverse vertical NPN. All conductivity types may be reversed from those listed, also.
