    摘要： Systems and methods are disclosed herein to provide reference generators. For example, in accordance with an embodiment of the present invention, a reference generator is provided for an electrical device, such as for example for an analog-to-digital converter. The reference generator may provide one or more reference signals having a common mode voltage that can track or be varied based on a common mode voltage of an input signal. Alternatively or in addition, the reference generator may provide reference signals for single-ended applications.

    摘要： 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.
