Abstract
A device of integration of an electric current received on an integration node, includes an operational amplifier, an integration capacitor, and a circuit for modifying an output voltage of the operational amplifier formed by a charge transfer circuit configured to be connected on the integration node and to transfer charges into the integration capacitor. The device also includes a comparison circuit configured to trigger the modification circuit at least once during the integration duration, and a storage circuit configured to store the number of triggerings which have occurred during the integration duration. The received electric current is calculated according to the output voltage as well as to the number of triggerings multiplied by the modification of the output voltage induced by the modification circuit.
