An analysis illustrates the loop nonlinear performance in a bang-bang PLL. A third-order equivalent model is deduced to give an approximate evaluation of the loop parameters. The architecture of the proposed phase det...
A semi-digital clock and data recovery (CDR) is presented. In order to lower CDR trace jitter and decrease loop latency, an average-based phase detection algorithm is adopted and realized with a novel circuit. Imple...

A fully pipelined 10 B/8 B decoder is presented with shorter critical path than before,and so its speed is improved greatly.Based on the proposed architecture,a 10 B/8 B decoder is implemented based on standard cells ...
A new configuration for delay cells used in voltage controlled oscillators is presented. A jitter comparison between the source-coupled differential delay cell and the proposed CMOS inverter based delay cell is given....
