Abstract | This thesis describes the architecture and components of a high-speed clock and data recovery (CDR) circuit. The CMOS circuits are presented for an integrated physical layer controller of a 622-Mb/s (OC-12) system. Simulations and experimental results are presented for the building blocks including novel designs for a current-controlled oscillator (CCO) and a charge pump. The CCO is based on a two-stage ring oscillator. It consists of parallel differential amplifier pairs which reliably generate the necessary phase shift and gain to fulfill the oscillation conditions over process and temperature variations. The schematics are implemented in C11 (0.13 µm CMOS). One contains partitioned building blocks of a phase-locked loop (PLL) which, together with an external capacitor loop filter. |
