Patent ID: 7839994

Claim:
A line driver comprising: a first driver circuit, wherein the first driver circuit is configured to generate a first component signal of a differential signal at a first polarity; a second driver circuit, wherein the second driver circuit is configured to generate a second component signal of the differential signal at a second polarity, and wherein the first and second component signals are biased via a bias signal to form biased first and second component signals; and an offset signal circuit in communication with the first and second driver circuits, wherein the offset signal circuit is configured to generate an offset signal for offsetting the biased first and second component signals, and wherein a combination of the offset and biased first and second component signals forms the differential signal, wherein a first average current of a sum of the biased first and second component signals for a set of transmit symbols is less than a second average current of the differential signal for the set of transmit symbols.
