Abstract:
Methods and apparatus are provided for digital linearization of an analog phase interpolator. Up to 2N desired phase values are mapped to a corresponding M bit value, where M is greater than N. A corresponding M bit value is applied to the phase interpolator to obtain a desired one of the 2N desired phase values. A linearized phase interpolator is also provided that accounts for process, voltage, temperature or aging (PVTA) variations.
