Abstract

A phase interpolator, multi-phase interpolation device, interpolated clock generating method and multi-phase clock generating method is related to a phase interpolator with a differential to single-ended converter, a load circuit, two differential pairs, a current source and at least a switch pair. By using the switch pair to control the current providing for the two differential pairs from the current source, and through regulating the load of the load circuit and/or the reference current of the current source, the intersection of a first signal and a second signal is in the overlap duration between a first input clock and a second input clock, so that uniform multi-phase output clock signal can be interpolated.
