ABSTRACT:
A pre-driver circuit includes a first stage to generate a first pre-driver signal and a second stage to generate a second pre-driver signal. The first and second stages are to generate the first and second pre-driver signals to cross at a point which reduces rise-and-fall mismatch in differential signal outputs from a current-mode driver.
