DC balance compensation for AC-coupled circuits










Image Number 2 for United States Patent #7620121.

A receiver has a first input port and a second input port both coupled to a differential amplifier through first and second input capacitors. A bias circuit coupled to the core side of the first input capacitor and to the core side of the second input capacitor is configured to provide a selected voltage to at least one of the first input and the second input of the differential amplifier. In one embodiment, a common mode bias circuit provides a common mode voltage to both inputs of a differential amplifier. In a particular embodiment, a run length detector monitors the output of the differential amplifier and provides a run length feedback signal or an average bit density feedback signal to the set the selected voltage between periods of data reception.
