Abstract
A fast locking phase locked loop includes a first integrator that provides a signal representing a function of the mathematical or ideal integral of the phase difference between an input signal and a feedback signal. A voltage controlled oscillator is coupled to the first integrator and provides a signal to a phase shifter that provides the phase shifted signal that represents a function of the phase of the signal from the VCO, and a function of the integral of the phase difference between the integrated signals.
