Receiver design with reduced variation

Abstract:

A receiver circuit holds an output voltage at a first output voltage level using a first device of a first type coupled between a first node and a first power supply node, and a second device of a second type coupled between the first node and the first power supply node. The first device is selectively enabled using an input signal. The second device is selectively enabled using a feedback signal. The second device is substantially larger than the first device. The receiver circuit switches the output voltage from the first output voltage level to a second output voltage level responsive to an input voltage level transitioning across a first threshold voltage level from a first input voltage level to a second input voltage level.
