Abstract: A phase locked loop includes a voltage controlled oscillator including a plurality of delay cells configured to respectively generate a plurality of clock signals having different phases and a harmonic lock detector configured to detect harmonic lock in the voltage controlled oscillator and to generate a reset signal in response. Remaining ones of the delay cells other than a first delay cell among the plurality of delay cells are reset in response to the reset signal.
