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.
