An improved fast acquisition PFD with zero blind zone for the PLL application
2014 IEEE International Conference on Electron Devices and Solid-State Circuits, EDSSC 2014, 2014.
An improved fast acquisition phase-frequency detector (PFD) for Phase-Locked Loop (PLL) is presented. The proposed PFD completely eliminates the blind zone, which is caused by the missing input edge during reset pulse. It has a linear output range and a saturated output when the phase error is in [0, π] and [π, 2π]. The simulation results...More
