ABSTRACT:
The present invention is an apparatus for determining the phase difference between a reference frequency signal and an input signal. The frequency sampling phase detector of the present invention may include a phase detector coupled with sample and hold circuitry. The frequency sampling phase detector of the present invention may reduce the frequency of an input signal suitable for proportional and linear phase detection by the phase detector. Advantageously, the frequency sampling phase detector of the present invention may reduce power consumption over conventional phase detectors in combination with frequency dividers.
