An improved fast acquisition PFD with zero blind zone for the PLL application

2014 IEEE International Conference on Electron Devices and Solid-State Circuits, 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.

A difference detector PFD for low jitter PLL [PDF]

ICECS 2001. 8th IEEE International Conference on Electronics, Circuits and Systems (Cat. No.01EX483), 2001
For high speed and low jitter PLL application, a new phase frequency detector (PFD) with difference detector is proposed. Because the proposed difference detector PFD (dd-PFD) doesn't have any feedback path in phase frequency detector circuit, it can be ...
