Abstract

Driver circuit for high voltage differential signaling. The circuit includes a first positive driver that generates a first positive transition at a first output in response to an input. The circuit also includes a first current element coupled to the first positive driver to enable generation of a current. Further, the circuit includes a first negative driver coupled to the first current element, and responsive to the input and the current, due to the first current element, to generate a first negative transition, at a second output, at a rate similar to that of the first positive transition.
