  • Phase detector and method for a shortening phase-error-correction pulse
    Patent number: 7471756
    Abstract: In a phase-locked loop (PLL), a phase detector receives a reference signal and a feedback oscillator signal, generates a phase-detect pulse having a first duration in response to one of the reference and feedback signals, and generates a phase-correction pulse having second, shorter duration in response to the phase-detect pulse. By shortening the phase-correction pulse, such a phase detector can reduce or eliminate the overcorrection period during which the phase-correction pulse is active after phase correction is achieved, and thus can reduce or eliminate the phase error that the overcorrection period may introduce into a PLL's oscillator signal.
