1. 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, i0, in terms of an input voltage, v, as i0=b0+b1v+b2v2+b3v3+b4v4 . . . ; 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, iL, in terms of a terminal voltage, vL, as iL=a0+a1vL+a2vL2+a3vL3+a4vL4, such that the nonlinear device and the nonlinear load are provided such that most nearly b0=a0, b1=ca1, b2=c2a2, b3=c3a3, bn=cnan where, c, is a constant, wherein the output of the nonlinear device substantially reduces nonlinearities of the nonlinear device and the nonlinear load.
