  • Dual loop phase locked circuit with sweep generator and compensation for drift
    Patent number: 5210509
    Abstract: A dual loop phase locked circuit is disclosed in which a first loop includes a phase detector, a filter, and a VCO; as a second loop includes a sweep voltage generator, a compensation circuit, and the filter of the first loop. Due to the compensation circuit, the VCO accurately tracks a signal from the sweep voltage generator, even though the filter has an electrical parameter that drifts with time and/or age and/or component selection.
