ABSTRACT:
An integrator system is disclosed which incorporates a feedback control loop to vary the linearity of the integrator's response. In the preferred embodiment an electrochemical coulometer is used which stores the integral of a current that is passed through it. Control is achieved by feeding back a control signal from the integrating circuit output to vary the rate at which current is passed through the coulometer.
