Abstract:
In this paper a new phase-frequency detector is proposed using transmission gates which can detect phase difference less than 500ps. In other word, the proposed Phase-frequency Detector (PFD) can work in frequencies higher than 1.7 GHz, whereas a conventional PFD operates at frequencies less than 1.1 GHz. This new architecture is designed in TSMC 0.13um CMOS Technology. Also, the proposed PFD achieves a capture range approximately twice that of conventional PFDs. The simulation results support the theoretical predictions. To validate correct performance of this novel PFD, it is then used in a conventional delay locked loop structure.
