Abstract: PURPOSE: A phase locked loop device capable of improving a phase noise property is provided to supply a high quality clock signal or a carrier, thereby maximizing the transmission efficiency of a mobile communication system. CONSTITUTION: A phase locked loop device(100) comprises a phase detector(110), a charge pump(120), a loop filter(130), a voltage control oscillator(140), a divider(150), and an injection locked frequency divider(160). The phase detector generates a phase difference signal which corresponds to the phase difference by comparing an inputted reference frequency clock and an oscillation signal which is divided and fed back. The charge pump produces a voltage signal with reference to the phase difference signal. The loop filter filters a signal of a specific frequency from the voltage signal. The voltage control oscillator produces the oscillation signal of a frequency which is changed according to the voltage level of an output signal of the loop filter. The divider divides the oscillation signal and provides the oscillation signal to the phase detector. The injection locked frequency divider divides the frequency of the oscillation signal in the rear end of the voltage control oscillator by an odd multiple and provides the divided frequency to the output signal.
