Abstract
In this paper, 20 Gb/s 1/4-rate and 40 Gb/s 1/8-rate burst-mode clock and data recovery (BMCDR) circuits are presented. The proposed inductorless gated digitally-controlled oscillator using a digitally frequency calibration loop is presented. These two BMCDR circuits have been fabricated in 0.13..m CMOS technology. For a PRBS of 27-1, the measured peak-to-peak jitter of the recovered clock for the 20 Gb/s 1/4-rate and 40 Gb/s 1/8-rate BMCDR circuits is 23.8 ps and 51 ps, respectively.
