Comparative Analysis of CMOS Phase Frequency Detector

This manuscripts presents the various design of almost significant electronic circuit used in modern wireless systems, known as Phase frequency detector. The phase-frequency detector is widely utilized in Phase-Locked-Loop (PLL) circuits, and its characteristics significantly affect PLL performance. In this work, different design topologies of PFD have been studied and evaluated their performance in terms of operating frequency, power dissipation, dead band, jitter and blind band.
