A Burst-Mode Digital Receiver With Programmable Input Jitter Filtering for Energ

Abstract

A full-rate burst-mode receiver that achieves fast on/off operation needed for energy-proportional links is presented. By injecting input data edges into the oscillator embedded in a classical Type-II digital clock and data recovery (CDR) circuit, the proposed receiver achieves i nstantaneous phase-locking and input jitter filtering simultaneously. In other words, the proposed CDR combines the advantages of c onventional feed-forward and feedback architectures to achieve energy-proportional opera
