ABSTRACT:
An amplifier/limiter circuit includes an amplifier providing an output signal having a potential range between ground and V.sub.D volts. A first pair of parallel connected complementary transistors have their principal conduction paths coupled between the output terminal of the amplifier and an amplifier/limiter output terminal. A second pair of parallel connected complementary transistors have their principal conduction paths coupled between the amplifier/limiter output terminal and a point of reference potential having a potential value between V.sub.D and ground. The amplifier/limiter output terminal provides a linear, amplified version of signal provided to the amplifier circuit over a limited range of potentials between V.sub.D and ground, which range is less than V.sub.D.
