Abstract
A differential cMOS push-pull buffer includes a pair of push-pull sections, a cMOS current source transistor connected to the push-pull sections for providing current thereto, and two cMOS trickle current transistors, each connected to an output node of a respective push-pull section for conducting a trickle current at the output node. In each push-pull section a trickle current enhances the speed of operation, thereby maintaining desirable attributes in output waveforms.
