Patent ID: 8085839

Claim:
An adaptive equalizer, comprising: one or more equalizing gain stages coupled to an input signal to be adaptively equalized; an automatic gain control circuit for controlling the gain of the one or more equalizing gain stages, the automatic gain control circuit having an AGC reference input; and a dual-output DC restoration circuit coupled to the output of the one or more equalizing gain stages; the dual-output DC restoration circuit including a first slicer circuit that generates a first output signal to recover low-frequency components of the input signal, the first slicer circuit being configured to introduce a hysteresis in the first output signal; the dual-output DC restoration circuit further including a second slicer circuit that generates a second output signal, the second output signal being coupled to the AGC reference input of the automatic gain control circuit, wherein the second slicer circuit is configured to introduce a lesser amount of hysteresis than the hysteresis introduced by the first slicer circuit.
