Abstract
The present invention in one embodiment provides a distortion creation and reduction circuit comprising a distortion circuit, a correction circuit, and a final signal combiner. The distortion circuit receives a first carrier signal and forms a first distorted carrier signal comprised of a first carrier signal and a first distortion signal component. The correction circuit receives a second carrier signal and forms a second distorted carrier signal comprised of a second carrier signal and a second distortion signal component. The first and second distorted carrier signals are formed and combined so that the first and second distortion signal components destructively combine and the first and second carrier signal components constructively combine. The distortion circuit is preferably comprised of a power amplifier. The correction circuit preferably comprises a distortion correction portion, a carrier correction portion, a correction signal combiner, and a correction amplifier.
