Differential level shifting buffer

摘要

A buffer includes two pairs of push-pull configured transistors as output drivers. One transistor in the first push-pull pair is controlled by an input signal and the second transistor in the first push-pull pair is controlled via a current mirror by a complement of the input signal. Similarly, one transistor in the second push-pull pair is controlled by the complement of the input signal and the second transistor in the second push-pull pair is controlled via another current mirror by the input signal.
