A phase interpolator includes a delay difference detector and a phase interpolation driver. The delay difference detector receives a delay code to detect a delay difference. The phase interpolation driver includes two or more driver blocks complementarily operating, and the phase interpolation driver interpolate two input signals in response to the delay difference to provide an interpolated output signal. Each of two or more driver blocks includes a plurality of unit drivers, each input of the unit drivers is commonly connected, and each delay of the two or more driver blocks is varied according to the delay difference.
