Abstract
A delay circuit includes a coarse delay circuit, a header circuit, and a phase mixing circuit. The coarse delay circuit is configured to delay a reference clock signal to generate a first clock signal and a second clock signal and to change each phase of the first clock signal and the second clock signal by double a unit phase. The header circuit is configured to receive the first clock signal and the second clock signal and to generate a first phase clock signal and a second phase clock signal, between which a phase difference corresponds to half of the unit phase. The phase mixing circuit is configured to mix phases of the first phase clock signal and the second phase clock signal to generate an output clock signal.
