초록
A lock detector and a clock generator including the same are disclosed. A lock detector includes a counter unit which counts a non-matching section of a first signal and a second signal to provide a count value, the first signal and the second signal being comparison result signals obtained by comparing a phase of a reference signal with a phase of a comparison signal, and a lock detection unit which outputs a lock detection signal based on a result of comparing the count value with the reference value. Accordingly, a lock state of the phase-locked loop can be detected rapidly and exactly.
