Abstract: A phase locked circuit includes an oscillator configured to generate an output clock signal, a first phase detector configured to detect a phase difference between an input clock signal and a feedback clock signal based on the output clock signal, a second phase detector having a wider phase locking range than that of the first phase detector and configured to detect the phase difference between the input clock signal and the feedback clock signal, and a charge pump controller configured to control an output current of a charge pump included in the second phase detector based on the phase difference detected by the first phase detector. When the phase difference between the input clock signal and the feedback clock signal is within the phase locking range of the first phase detector, the oscillator and the first phase detector are connected to each other.
