Abstract
A circuit for reducing negative ground bounce on the ground reference of a CMOS circuit having an input terminal and an output terminal includes an output buffer having an input coupled to the input terminal of the circuit and an output coupled to the output terminal of the circuit. A NOR gate has first and second inputs respectively which are coupled to the input and output terminals of the circuit. An injector circuit is coupled to an output of the NOR gate and to the input terminal of the circuit for providing a predetermined current to the output terminal of the circuit.
