  • Abstract
    A fully symmetrical phase-frequency detector (fs-PFD) is proposed in this paper. Because there is no feedback path in the fs-PDF circuit, it can be operated above 1GHz. Some improvements are made to get a dead zone of only 12 ps. Phase locked loop (PLL) using the fs-PFD has a reduced locking time and an output signal frequency with little jitter.
