Design of Delay Locked Loop with Frequency Division Technique

Wenyuan Li, Yurong Cao

Abstract— Design of delay locked loop (DLL) with frequency division technique is presented. The proposed pseudo-differential delay cell increases the input clock frequency. To avoid the false locking or harmonic locking problem, a simple start-control signal is added. The DLL design are implemented by IBM 0.13μm CMOS process. The static phase error of the DLL is 2.6ps at 3GHzand 8.5ps at 5GHz, respectively. The peak-to-peak jitter values at 3GHz and 5GHz are 3.3ps and 1.7ps.The supply voltage is 1.2V.

Index Terms— delay locked loop, charge pump, phase frequency detector, delay cell, frequency division.
