Abstract
A BICMOS driver circuit is provided having high input impedence and high output current drive with low static power dissipation that provides supply voltages and full logic output voltage swing for circuits having submicron dimensions. An inverter circuit is coupled to a voltage divider circuit and the input terminal for inverting the input signal. A complementary emitter follower circuit is coupled to an output terminal for providing a digital output signal. A current source circuit is coupled to the complementary emitter follower circuit and the input terminal for sourcing current to the complementary emitter follower circuit in response to the input signal. A bipolar bias circuit is coupled to the complementary emitter follower circuit and the inverter circuit for biasing the complementary emitter follower circuit in response to an inverted input signal.
