ABSTRACT:
An AC-coupling phase interpolator and a DLL using the same are provided. The AC-coupling phase interpolator includes a coupling capacitor generating and outputting a coupling signal by AC-coupling to an interpolation signal obtained by phase-interpolating an input signal. Thereby, it is possible to correct duty of an input signal and adjust the level of an output signal.
