ABSTRACT:
An adaptive equalizer may include one or more equalizing gain stages coupled to an input signal. An automatic gain control circuit may be used to control the gain of the one or more equalizing gain stages, the automatic gain control circuit having an AGC reference input. A dual-output DC restoration circuit may be coupled to the output of the one or more equalizing gain stages for generating a first output signal using a first hysteresis slicer that DC restores the input signal and for generating a second output signal using a second hysteresis slicer that is coupled to the AGC reference input of the automatic gain control circuit, wherein the second hysteresis slicer introducing less hysteresis than the first hysteresis slicer.
