Abstract
A method is described that level shifts a differential signal to produce a first signal and level shifts the logical inverse of the differential signal to produce a second signal that is the logical inverse of the first signal. The method then inverts the first signal and inverts the second signal. The method then inverts the first signal and the inverted second signal together and inverts the second signal and the inverted first signal together.
