Abstract :
A fully differential, quasi-mixer based, half-rate clock recovery PLL has been implemented in a 0.18-μm CMOS technology, and is optimized for high-speed of operation at 13 Gbit/s. A special differential varactor tuning arrangement is used to provide a wide operating frequency range from 6.2 GHz to 7.2 GHz, with a power consumption of 69 mW.
