ABSTRACT:
An internally compensated monolithic integrated operational amplifier circuit has a differential input stage, balanced complementary common base stage, a complementary compound emitter-follower stage, and a push-pull output stage. The push-pull output stage includes complementary common emitter transistors, the base electrode of each transistor connected to a transistor connected in common base configuration. Bandwidth and slew rate are enhanced by a feed-forward capacitor connected between the amplifier inverting input and the input to the push-pull output stage and also by a range extender network connected between the output of the input differential stage and the input of the push-pull output stage. Internal bias voltages are referenced to the potential applied to the amplifier noninverting input by means of a voltage follower circuit which is interactively connected with a diode chain and current sources.
