Abstract
A continuous time equalizer for equalizing an input signal using a feedforward equalizer portion and a feedback equalizer portion is provided that includes: a slicer operable to make bit decisions on a combined output from the feedforward and feedback equalizer portions; an adaptive delay circuit operable to delay the combined output to form a delayed output; and a controller operable to control the delay provided by the adaptive delay circuit such that a first group delay through the slicer and a second group delay through the adaptive delay circuit in response to a sinusoidal form of the input signal are substantially equal.
