Abstract

PURPOSE:To enable to make phase comparison in high speed, by exclusive logical sum between the output sampling the input signal and the original input signal. CONSTITUTION:The output 2 from a voltage controlled oscillator 6 is frequency- divided at a flip-flop 13. The output frequency-divided is input to the terminal D of a flip-flop 14. The input clock 1 is input to the terminal C of the flip-flop 14. The input signal at the terminal D is sampled at the leading of the input clock. The Q and Q' outputs of the flip-flop 13 and the flip-flop 14 are input to an exclusive logical sum 15 to obtain the phase comparison output. Since the phase comparison output is obtained at the leading change point of the output 2 and the clock 1 of the voltage controlled oscillator 6, the operating range in high speed can be made in any of the clock 1.
