Abstract (en)
[origin: WO2019166465A1] This device (100a) for integrating an electric current (I) received on an integration node (E) comprises: - an operational amplifier (62); - an integration capacitor (64); - a circuit (105a) for modifying an output voltage (V OUT ) of the operational amplifier performed by a load transfer circuit configured to be connected on said integration node and to transfer loads in said integration capacitor; - a comparison circuit (74) configured to initiate said modification circuit at least once during said integration duration (T int ); and - a storage circuit configured to store said number of initiations that occurred during said integration duration. The received electric current is computed as a function of said output voltage as well as of said number of initiations multiplied by said modification of said output voltage induced by said modification circuit.
