Abstract
A driver circuit includes a differential amplifier for receiving an input signal, and first and second transistors of different conductivity types. The first and second transistors are connected serially between two power supply terminals in a form (source follower) in which the sources of the transistors are connected to an output point, for push-pull driving the output point in response to an output signal from the differential amplifier.
