| Abstract: | A digital frequency/phase detector is described. Logic design and layout/circuit design are discussed in detail. An operating frequency of 8 MIIz and phase detection sensitivity of 0. 12 V/ rad were obtained for the circuit. With high reliability and good stability, this circuit is useful in digital phase locked loops. |
