Abstract (en)
[origin: WO2019081562A1] The invention relates to an optical sensor (1), in particular an artificial retina, with at least one photosensitive cell, each cell including: - an integration capacitor (Cm), - a reading circuit (10) of which the operation depends on the charge of the integration capacitor (Cm), - at least one MOS transistor (3; 31; 32) operating below the threshold, the drain-to-source current of which influences the charge of the integration capacitor (Cm), - at least one photodiode (2; 21; 22) operating in photovoltaic mode, connected to the gate of this transistor, so that the drain-to-source current of the MOS transistor depends on the optical power received by the photodiode.
