Provided is a multi-phase clock generator which is not influenced by a mismatch and of which a maximum frequency is not limited. The multi-phase clock generator includes a first delay line, a second delay line, a phase detector, and an up/down counter. The first delay line generates a first clock signal by delaying an input clock for a first delay time. The second delay line generates a second clock signal by delaying the input clock for a second delay time in response to a control signal. The phase detector detects a phase difference between the first and second clock signals. The up/down counter generates the control signal in response to an output of the phase detector.
