Abstract
This paper describes a reference-less 4 Gbps Clock and Data Recovery (CDR) circuit. A novel compensation technique is used to initialize the Voltage Controlled Oscillator´s (VCO) frequency close to the data rate. A new method for the theoretical estimation of filtered phase noise power responsible for bit error is presented and is verified experimentally. CDR is implemented in 65 nm CMOS technology on 1.8 V supply and consumes 50 mA current.
