Adaptation Algorithm of Decision Feedback Equalizer with First Post-Cursor Cancellation for Backplane Serial Links

Abstract

In multi-gigabit per second systems, due to speed limitation, decision feedback equalization with first post-cursor cancellation can cause additional pattern dependent jitters with conventional LMS adaptation algorithm. Combining LMS algorithm and edge equalization, effects of first tap feedback delay is relieved and more compromised timing and voltage… (More)
