Abstract

A driver circuit in which a signal received at an input gate provides, at the output of the circuit, a signal having fast rise and fall times and high voltage swings. The input stage of the circuit includes two transistors coupled in a complementary emitter follower arrangement and the output stage of the circuit includes two transistors in a complementary common emitter amplifier arrangement. The circuit includes separate high speed and low speed signal paths.
