Title: Amplifier with current gain inversely proportional to transistor h.sub.fe

Abstract: A first transistor of a first conductivity type connected as a common-base amplifier in the collector-to-base feedback connection of a second transistor of a second conductivity type, complementary to the first conductivity type, exchanges base current with a third transistor of the second conductivity type. The collector current of the third transistor is proportional to that of the second transistor by a factor substantially equal to 1/h.sub.fe, where h.sub.fe is the common-emitter forward current gain of the first transistor.
