Abstract
A differential driver circuit includes a differential driver configured to drive an output signal based upon a positive leg pull up signal, a positive leg pull down signal, a negative leg pull up signal, and a negative leg pull down signal. A first pre-driver includes a first driver configured to receive a positive leg signal and a first voltage divider coupled to an output of the first driver and configured to produce the first pull up signal and the first pull down signal. A second pre-driver includes a second driver configured to receive a negative leg signal and a second voltage divider coupled to an output of the second driver and configured to produce the second pull up signal and the second pull down signal. The differential driver may include a positive leg and a negative leg, each having a pull up transistor and a pull down transistor.
