  • Apparatus and method thereof for compensating for gain changes of N-PAM modulate signals
    Patent number: 8837573
    Abstract: A method for compensating for gain changes of an N-level pulse amplitude modulation (PAM-N) modulated signal. The method comprises comparing the PAM-N modulated signal to N?1 configurable thresholds, wherein the input PAM-N modulated signal is also equalized and the N?1 configurable thresholds are N?1 different voltage levels; tracking gain changes in the input PAM-N modulated signal by comparing the input PAM-N modulated signal to a compensation threshold; and adjusting a level of the at least one of the N?1 configurable thresholds of the N?1 comparators based on an output of the compensation comparator, thereby offsetting a crossing point of the at least one comparator respective of the at least one of the N?1 configurable thresholds to compensate for gain changes in the input PAM-N modulated signal.
