Title
A Calibrated Phase/Frequency Detector for Reference Spur Reduction in Charge-Pump PLLs.
Abstract
This brief presents a new technique for minimizing reference spurs in a charge-pump phase-locked loop (PLL) while maintaining dead-zone-free operation. The proposed circuitry uses a phase/frequency detector with a variable delay element in its reset path, with the delay length controlled by feedback from the charge-pump. Simulations have been performed with several PLLs to compare the proposed cir...
