Abstract: An automatic frequency control device is provided to lock a frequency of an oscillation signal of an oscillator by comparing the frequency of the oscillation signal divided into 1/N and a reference signal. A divider(220) divides an oscillation signal of an oscillator into 1/N. A phase alignment unit(230) produces a plurality of reference signals with different phases by using the reference signals generated from a reference signal generator. The phase alignment unit selects one reference signal among the produced reference signals according to an output signal of the divider. A frequency comparator(240) compares the frequency of the oscillation signal outputted from the divider with the reference signal selected by the phase alignment unit. A frequency controller(250) controls the oscillation frequency of the oscillator according to the comparison result of the frequency comparator. A frequency changing unit changes the oscillation frequency of the oscillator according to the frequency controller.
