Abstract

A buffer circuit includes an amplifier, a pass gate circuit and a level shifter. The pass gate circuit communicates an input signal to the amplifiers and includes a terminal to control the communication. A level shifter furnishes a control signal to the terminal of the pass gate circuit and regulates the control signal based on a magnitude of the input signal.
