An amplifier arrangement for reducing nonlinearities in the response of an output transducer coupled to the amplifier arrangement is disclosed. The arrangement comprises a sensor coupled to a moving member of the transducer, a precision rectifier circuit having a signal to be amplified and an output signal from the sensor as inputs for comparing the signal to be amplified and the sensor output signal and for producing an error signal proportional to the difference between the two signals and a voltage controlled amplifier for amplifying the signal to be amplified whose gain is controlled by the error signal.
