A circuit comprises a cycle-cycle detector, configured to receive a synthesized clock signal, and detect a cycle difference index signal between any two neighboring cycles of the synthesized clock signal, wherein the synthesized clock signal is combined by a plurality of phase shifted signals; a demultiplexer connected to the cycle-cycle detector, configured to convert the cycle difference index signal into a plurality of parallel data signals; and a first state machine, connected to both the demultiplexer and the cycle-cycle detector, configured to generate a tuning signal based on the parallel data signals, and feed the tuning signal back to the cycle-cycle detector; wherein the cycle-cycle detector is further configured to adjust delay time of the synthesized clock signal according to the tuning signal.
