ABSTRACT:
A method and apparatus for an adjustable phase interpolator is provided. The adjustable phase interpolator includes a phase interpolator circuit that has a voltage input and a voltage output. The adjustable phase interpolator further includes a controllable capacitive load coupled to either the input or the output of the phase interpolator circuit. The controllable capacitive load is designed to add or subtract capacitance to the adjustable phase interpolator.
