Abstract
A half-rate bang-bang phase and frequency detector (BBPFD) is presented for continuous-rate clock and data recovery (CDR) circuits. The proposed half-rate BBPFD not only preserves the advantages of conventional BBPDs, but also has the infinite unilateral frequency detection range. To verify the proposed circuit, a continuous-rate CDR circuit with the proposed BBPFD has been fabricated in a 0.18um CMOS process. It can recover the NRZ data with the bit rate ranging from 622Mbps to 3.125Gbps. The measured bit-error rate is less than 10-12. The core area is 0.33 × 0.27 mm2 and the power consumption is 80mW from a 1.8V supply. © 2007 IEEE.
