Summary:Circuitry for controlling a phase-lock loop using a charge-pump phase detector is shown to comprise a phase detector network in combination with an operational amplifier connected to selected output signals from such network to produce a bipolar D.C. signal indicative of the phase difference between signals applied to such network, one of the signals being at a frequency half that of the other.
