Edge signal restoration circuit and method

摘要

An edge signal restoration circuit and method to enhance an edge of a signal decreases a rise and fall time of a propagating signal during transitions between logic states. The edge signal restoration circuit includes a first circuit to detect an edge of an input signal and to output a detection signal, and a second circuit to drive a next state of the input signal in response to the detection signal at approximately the same time as the first circuit detects the edge of the input signal. The edge signal restoration method detects a transition of the signal between a current state and a next state, and drives the next state onto the signal during its transition to that next state.
