ABSTRACT:
A system and method for transmitting information includes a first driver circuit configured to generate a first component signal of a differential signal at a first polarity. The system includes a second driver circuit configured to generate a second component signal of the differential signal at a second polarity. The first and second component signals are biased to form biased first and second component signals. A differential amplitude of a combination of the biased first and second component signals is less than a corresponding differential amplitude of the differential signal. The system includes an offset signal circuit in communication with the first and second driver circuits. The offset signal circuit is configured to generate an offset signal for offsetting the biased first and second component signals. A combination of the offset and biased first and second component signals forms the differential signal.
