Abstract
A BIMOS driver circuit and method in which a push-pull pair of PNP-NPN bipolar transistors replaces the middle CMOS inverter stages in a circuit for driving a capacitive load. The rise and fall times of the circuit are made symmetrical by feeding back driver circuit output to operate a feedback transistor which removes the base charge stored in a PNP transistor of the bipolar push-pull pair, and maintains low propagation delay.
