HIGH-SPEED SIGNALING SYSTEMS AND METHODS WITH ADAPTABLE, CONTINUOUS-TIME EQUALIZATION

摘要

A receiver includes a continuous-time equalizer, a decision-feedback equalizer (DFE), data and error sampling logic, and an adaptation engine. The receiver corrects for inter- symbol interference (ISI) associated with the most recent data symbol (first post cursor ISI) by establishing appropriate equalization settings for the continuous-time equalizer based upon a measure of the first-post-cursor ISI.
