Abstract
An embodiment of an apparatus for nonlinearity compensation is disclosed. For an embodiment, a pre-distorter is coupled to receive a first signal. The pre-distorter is configured to convert first values of the first signal into second values for a second signal. The pre-distorter includes a converter for converting the first values to the second values. A phase interpolator is coupled to receive the second signal. The second values are associated with nonlinearity of the phase interpolator. The phase interpolator is configured to provide an interpolated output from the second signal. The second signal is adjusted for the nonlinearity of the phase interpolator by use of the second values.
