A CMOS merged CDR and Continuous-Time Adaptive Equalizer

摘要

We present a low-voltage merged CDR and cntinuous-time adaptive equalizer capable to compensate the attenuation of a SI-POF channel while at the same time synchronizing and regenerating the incoming signal in a single stage. The system operates at 1.25 Gbps for NRZ modulation through a 50-m SI-POF channel and it is designed in standard 0.18-μm CMOS fed at 1 V with a power consumption of 43.4 mW.
