Abstract

Phase/frequency detectors deliver output in the form of three-state, digital logic. Charge pumps are utilized to convert the timed logic levels into analog quantities for controlling the locked oscillators. This paper analyzes typical charge-pump circuits, identifies salient features, and provides equations and graphs for the design engineer.
