Abstract
A DC restoration circuit to correct for baseline wandering in a data receiver is provided. A voltage correction circuit is connected to the received data line to adjust the voltage level of the received data dynamically. The voltage correction circuit is controlled by a feedback circuit which includes a voltage detection circuit configured to detect the peak voltage levels or envelope of the received data. This detected level is then compared to a reference level, and the result of the comparison is used as a control signal for the voltage correction circuit.
