Abstract
A circuit for assisting signal transitions on a wire, and a method thereof. The circuit includes a first subcircuit that causes a first transistor that is coupled to the circuit's output to turn on during a rising transition and then turn off. The first transistor drives the output to a high state to assist in the rising transition. The circuit also includes a second subcircuit that causes a second transistor that is coupled to the circuit's output to turn on during a falling transition and then turn off. The second transistor drives the output to a low state to assist in the falling transition.
