Abstract
A system and method for use in cancelling phase jitter in a Phase Locked Loop (PLL) circuit. A phase jitter canceller receives a phase error signal having phase jitter centered around a center frequency. A frequency and phase control circuit determines the phase of a particular component of phase jitter and an amplitude control circuit determines the amplitude of the particular component of phase jitter in the signal. The output of the phase jitter canceller provides an estimate of the particular component of phase jitter. A parallel arrangement of phase jitter cancellers is also provided for use in cancelling several components of phase jitter.
