Popis: This paper presents a 120-to-520Mb/s clock and data recovery (CDR) circuit that utilizes pulse width modulation (PWM) signaling scheme. Compared to the conventional approach, the proposed retiming scheme improves sampling margin over 200%, which results in lower BER. The proposed idea has been simulated in a 65nm CMOS technology. The post layout simulation result has shown that recovered clock and data have 3.42ps and 7.55ps rms jitter at 500Mb/s data rate. The CDR circuit consumes 1.97mW (1.2V supply) at 500Mb/s of MIPI M-PHY signaling format.
