Abstract
An input buffer circuit includes a tracking circuit that produces a tracking signal and an inverter including a cascade of low voltage switching devices coupled to an output of the tracking circuit. The tracking signal follows a first signal during a first time period and a second signal during a second time period. The tracking circuit is configured to reduce an input high voltage/input low voltage (VIH/VIL) spread.
