Abstract
An electric signal processing circuit with an operational amplifier having a signal input, a feedback input and a signal output, and a nonlinear circuit device having a characteristic with a distortion-producing nonlinearity and located in the input signal circuit or in the feedback circuit of the operational amplifier, wherein a compensating circuit device having a characteristic with generally the same nonlinearity as the characteristic of the nonlinear circuit device is disposed in the feedback circuit or in the input signal circuit of the operational amplifier for compensating the distortion of the nonlinear circuit device.
