Abstract
The current-to-voltage converter includes an input for the current to be converted, an output for the converted voltage, a current-to-voltage conversion resistor arranged between the output and a reference potential, a processing circuit including a transistor, the input being connected to the output via the transistor, a twin circuit including components identical to and disposed in a similar way to those of the processing circuit, a voltage follower connected at the input to the processing circuit and at the output to the twin circuit, and means for reinjecting the current at the output of the follower into the processing circuit.
