Abstract
A frequency phase comparator comprises: first flip-flop with reset terminal to receive the first cycle signal on clock terminal; first delay mechanism to delay the first flip-flop output withpredetermined time t1; second flip-flop with reset terminal to receive the second cycle signal on clock terminal; second delay mechanism to delay the second flip-flop output withpredetermined time t2; logical circuit to perform logical operation between output of the second delay mechanism and the above first delay mechanism; synthesis mechanism to synthesize output of the above first flip-flop and output of the second flip-flop; linking output of the above logical circuit on individual reset terminal of the above first flip-flop and the above second flip-flop.
