Abstract: A full wave rectifier circuit comprising a differential amplifier which drives a rectifier stage via a driver stage and to which negative feedback is applied. A signal current to be rectified is applied to an input of the differential amplifier. This current flows directly to the output of the rectifier stage during one half-cycle and is applied to said rectifier stage via a first current mirror during the other half-cycle. The supply current of this current mirror together with the supply current of the driver stage are delivered by a current source. A reduction of the voltage offset is obtained in that the current source is a controllable current source, which is controlled by a current derived from the output current of the first current mirror in such a way that the supply current of the current mirror corresponds to the varition in the current from the current source caused by the control action.
