Phase interpolator for high-speed serial data transceiver systems and related methods

摘要

The invention refers to 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.
