US 11,637,356 B1 · Dynamic gate-overdrive voltage boost receiver

Abstract

In certain aspects, a receiving circuit includes a splitter, a first receiver, a second receiver, and a boost circuit. The splitter is configured to receive an input signal, split the input signal into a first signal and a second signal, output the first signal to the first receiver, and output the second signal to the second receiver. In certain aspects, the voltage swing of the input signal is split between the first signal and the second signal. The boost circuit may be configured to shift a supply voltage of the second receiver to boost a gate-overdrive voltage of a transistor in the second receiver during a transition of the input signal (e.g., transition from low to high). In certain aspects, the boost circuit controls the gate-overdrive voltage boosting based on the first signal and the second signal.
