Abstract
In one aspect, the present invention is directed to a compensator for compensating linearity errors, such as harmonic distortion and intermodulation distortion, in devices. The compensator includes a means for phase-shifting and a means for exponentiation to generate a compensation signal such that the linearity error distortion signals are canceled in the system output while maintaining the desired fundamental signal. Another aspect of the invention is directed to methods for calibrating linearity error compensators.
