ABSTRACT:
A device for differential-mode processing of an incident voltage relative to a reference voltage includes a differential circuit including a voltage/current conversion block having a differential input, designed to receive the incident voltage at a first input and the reference voltage at a second input. A current amplification block includes a gain module and a current subtraction module. A current/voltage conversion block includes an operational amplifier with differential transimpedance supplied with a common-mode voltage, receiving the two currents output from the amplification block at its input, and delivering two calibrated opposing voltages at its output that are centered around the common-mode voltage.
