ABSTRACT:
A digital phase detector has a plurality of first delay elements through which a first clock is delayed, a plurality of second delay elements through which a second clock is delayed, and a plurality of data holding circuits. The data holding circuits latch the first clock successively delayed through the first delay elements and hold a digital value representing a relative phase difference, in accordance with the second clock successively delayed through the second delay elements. Therefore, the phase detection resolution of the digital phase detector can be improved.
