Patent ID: 8452001

Claim:
A line driver comprising: a first driver circuit configured to receive a first transmit signal, and generate a first component signal having a first polarity based on (i) the first transmit signal, (ii) a bias signal, and (iii) an offset signal; a second driver circuit configured to receive a second transmit signal, and generate a second component signal having a second polarity based on (i) the second transmit signal, (ii) the bias signal, and (iii) the offset signal, wherein the second polarity is different than the first polarity; and a first summing circuit configured to sum the first component signal and the second component signal to generate a first differential signal, wherein a first average current of the first differential signal for a plurality of symbols is greater than a second average current of a second differential signal for the plurality of symbols, wherein the second differential signal is generated by summing a first biased signal and a second biased signal, and wherein the first biased signal is generated by biasing the first transmit signal based on the bias signal, and wherein the second bias signal is generated by biasing the second transmit signal based on the bias signal.
