چکیده
This paper presents the design of a clock and data recovery circuit having a high data rate of 9.95328 Gb/s by using delay locked loop with Switched Capacitor (SC) filter to improve the jitter transfer function and jitter tolerance as it has high Q and low center frequency. From the results it is seen that the besides the conventional DLL circuit , the circuit using SC filter of fc= 311.04 MHz and Q=500 provides very low cut off frequency. KeywordsSwitched Capacitor filter; Delay locked loop; VCDL.

Settling time is one of the most important parameter in design of DLLs. In this paper we propose a new high speed with low settling time Delay Locked Loop (DLL) in which a digital signal processor (DSP) is used instead of using phase-frequency detector, charge pump and loop filter in conventional DLL. To have better settling time, PRP conjugate gradient algorithm is used to optimize delay of ea...
