Abstract :
A gated current-controlled oscillator (GCCO) based topology is used to implement a low-power multi-channel clock and data recovery (CDR) system in a 0.18μm digital CMOS technology. A systematic approach is presented to design a reliable and low-power system based on the required specifications. Behavioral simulations are also used to estimate the achievable bit error rate (BER), jitter tolerance (JTOL), and frequency offset tolerance (FTOL) of the proposed CDR. Using a single 1.8 V supply voltage, the proposed 20Gbps 8-channel CDR consumes only 70.2mW or 3.51 mW/channel/Gbps while occupies 0.045mm2 silicon area.
