Title (EN) SYSTEM, METHOD, AND DEVICE FOR SUPPRESSION OF DARK CURRENT
(FR) SYSTÈME, PROCÉDÉ, ET DISPOSITIF DE SUPPRESSION DE COURANT D'OBSCURITÉ
Abstract: front page image
(EN)A method, system and device for reducing dark current, by clamping the voltage across the photodiode to about zero using local storage of charge, in an array of pixel cells in which each pixel cell has a photodiode configured to receive light and generate a photocharge during an integration period.
(FR)La présente invention concerne un procédé, un système et un dispositif pour réduire le courant d'obscurité, en fixant la tension à la photodiode à environ zéro en utilisant un stockage local de charge, dans une série de cellules de pixel dans laquelle chaque cellule de pixel possède une photodiode conçue pour recevoir de la lumière et pour générer une photo-charge durant une période d'intégration.
