Abstract: A system and method for enhancing the dynamic range of a receiver without degrading the signal to noise ratio of an incoming signal is disclosed. In one embodiment, an enhanced dynamic range receiver for receiving an incoming signal and processing the incoming signal comprises a plurality of VGAs alternately connected in series with a plurality of equalizers to form a VGA-equalizer chain, the VGA-equalizer chain adapted to receive the incoming signal and operable to generate a first analog signal, a first PD adapted to receive the first analog signal and operable to adjust the equalizers' coefficient values, and a second PD adapted to receive a second analog signal from a selected node in the VGA-equalizer chain and operable to adjust the gain of the VGAs.

Abstract: An adaptive equalization method and system for automatically adjusting an equalizer to compensate a signal's frequency dependent loss is disclosed. The method comprises setting the equalizer's initial coefficient value, receiving an equalized signal, identifying a positive to zero transition of the equalized signal, generating a common mode voltage from the equalized signal, and determining the equalized signal's tail settling voltage. The method further comprises comparing the equalized signal's tail settling voltage to the common mode voltage, determining if the signal is over equalized or under equalized based on the comparison, and adjusting the equalizer's coefficient value based on whether the signal is under equalized or over equalized.
