摘要:This article reports a half-rate single-loop bang bang clock and data recovery (BBCDR) circuit without the need of reference and frequency detector (FD). Specifically, we propose a deliberate-current-mismatch charge-pump pair to enable fast and robust frequency acquisition without identifying the frequency error polarity. This technique eliminates the need for a complex high-speed data or clock path during the frequency acquisition, resulting in significant power savings. Prototyped in 28-nm CMOS, the BBCDR circuit automatically tracks a four-level pulse-amplitude modulation (PAM-4) input...
