Abstract
A receiver converter circuit included in a computer system may receive multiple signals that encode a serial data stream that encode multiple data symbols. To correct for baseline wander, the receiver circuit may generate a disparity signal that is used to control the application of a differential voltage to the multiple signals. The receiver circuit may also employ the disparity signal to generate a gradient against which the magnitude of differential voltage is calibrated.
