Phase interpolator device and method

A phase interpolation system, comprising:

• a stage controller adapted to produce a plurality of stage control signals in response to a phase control input;
• a plurality of reference stages, each adapted to convert one of a plurality of reference signals into a corresponding component signal in response to a respective one of the stage control signals, wherein each of the reference signals has a distinct phase;
• and
• a combining node adapted to combine the component signals into an output signal having an interpolated phase, wherein the stage controller is a phase control signal rotator adapted to adjust the plurality stage control signals such that the output signal is phase aligned with a serial data signal.

A phase interpolation system, comprising:

• a plurality of reference stages, each adapted to convert one of a plurality of reference signals into a corresponding component signal in response to a respective one of a plurality of stage control signals, wherein each of the reference signals has a distinct phase, and wherein each of the plurality of reference stages comprises
• a conversion module adapted to convert the corresponding reference signal into the corresponding component signal according to a scaling factor, and
• a plurality of scaling modules coupled to the conversion module;
• and
• a combining node adapted to combine the component signals into an output signal having an interpolated phase.
