  • Phase detector circuit having latched output characteristic
    Patent number: 4901026
    Abstract: A phase detector circuit for providing an output indicative of the phase relationship between two input signals. The output of the phase detector responds rapidly to changes in the phase relationship between the input signals and avoids "cycling" when this phase relationship is less than -2.pi. or greater than 2.pi.. The phase detector includes circuit means for detecting when the phase relationship is outside a desired range such as proportional phase detectors which operate in combination with a differential type phase detector for providing the required output.
    Type: Grant

  • Circuit providing improved lock-in for a phase-locked loop
    Patent number: 4801896
    Abstract: Disclosed is a latching differential phase detector for improving a slew rate and preventing false phase lock due to cycling. The system combines 2.pi. proportional phase detectors to cover a 4.pi. range. The lock monitors of the phase frequency detectors control a differential phase detector to provide positive latching.
