Patent ID: 6853248

Claim:
An apparatus for substantially reducing nonlinear distortion, the apparatus comprising: a first nonlinear device having an input and an output; a second nonlinear device having an input and an output, the inputs of the first and second nonlinear devices are in communication with an input signal; an attenuator having an input in communication with output of the first nonlinear device and an output; a first subtractor having a first input in communication with the output of the second nonlinear device, a second input in communication with the output of the attenuator and an output; wherein the first subtractor subtracts an output of the second nonlinear device from an output of the attenuator; a third nonlinear device having an input in communication with the output of the first nonlinear device and an output; a fourth nonlinear device having an input in communication with output of the first subtractor and an output; and a second subtractor having a first input in communication with the output of the third nonlinear device, a second input in communication with the output of the fourth nonlinear device and an output, wherein the second subtractor subtracts the output of the fourth nonlinear device from the output of the third nonlinear device to form a final output signal.
