Abstract
A phase interpolator may include a decoding logic circuit. The decoding logic circuit may take as input an input control code and an update clock. The decoding logic circuit may generate one or more outputs which may be input to a retiming circuit. The retiming circuit may generate retimed outputs which may be input to a delay modulation circuit. The delay modulation circuit may generate a delayed clock select control signal and a delayed phase select control signal. The delayed clock select control signal and delayed phase select control signal may be input to a phase interpolator circuit and may generate an output clock based on two or more multi-phase input clocks. The delayed clock select control signal and delayed phase select control signal may eliminate overshoot and undershoot events in the output clock.
