Patent ID: 6853247

Claim:
An apparatus for substantially reducing nonlinear distortion, the apparatus comprising: a nonlinear device having an input and an output, the nonlinear device having a Taylor series expansion describing an output current, i 0 , in terms of an input voltage, v, as i 0 =b 0 +b 1 v+b 2 v 2 +b 3 v 3 +b 4 v 4 . . . ; and a nonlinear load having an input in communication with the output of the nonlinear device and in communication with a final output, the nonlinear load has a Taylor series expansion describing a current through the nonlinear load, i L , in terms of a terminal voltage, v L , as i L =a 0 +a 1 v L +a 2 v L 2 +a 3 v L 3 +a 4 v L 4 , such that the nonlinear device and the nonlinear load are provided such that most nearly b 0 =a 0 , b 1 =ca 1 , b 2 =c 2 a 2 , b 3 =c 3 a 3 , b n =c n a n where, c, is a constant, wherein the output of the nonlinear device substantially reduces nonlinearities of the nonlinear device and the nonlinear load.
