    摘要: An output distortion circuit includes a first transistor arrangement receiving a nonlinear current associated with a nonlinear differential error signal. The first transistor arrangement produces a reflected base current that is applied to one side of a differential input pair. A second transistor arrangement eliminates the nonlinear differential error signal by producing a replicated base current that replicates the reflected base current. The replicated base current is applied to an opposite side of the differential input pair thus the output distortion cancellation circuit creating a deflection of approximately equal magnitude to the reflected base current so as to eliminate the nonlinear differential error signal.
