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.
Claims19
A buffer circuit comprising:
- an amplifier;
- a pass gate circuit to communicate an input signal to the amplifier, the pass gate circuit including a terminal to control the communication;
- and
- a level shifter to furnish a control signal to the terminal of the pass gate circuit and regulate the control signal based on a magnitude of the input signal.
