Abstract
A receiver with baseline wander correction for correcting a received input signal. The receiver includes first and second biasing resistor networks configured to receive first and a second signal of the received input signal, and to produce a first correction signal and a second correction signal. A comparator is employed to compare the first and the second correction signals in order to produce a control signal. The receiver also has comparison logic and compensation control circuitry. The comparison logic generates a logic signal according to the first and the second correction signals. Finally, the compensation control circuitry produces a compensation signal and provides it to respective output terminals of the first and the second biasing resistor networks so as to correct respective DC values of the first and the second correction signals.
