ABSTRACT:
A phase detector is disclosed that eliminates frequency ripple in a phase-locked loop circuit. The detector includes first and second circuits for providing UP and DOWN signals respectively. It also includes a delay element for setting the duration of the DOWN signal so as to eliminate phase jitter and static phase offset.
