Abstract An optical sensor (100) comprises an array of pixels, wherein each pixel comprises a photodiode (111) configured to receive an optical signal and a floating node (113) coupled to the photodiode (111). At least one sensing path (114) is capacitively coupled to the floating node (113) of at least one of the pixels (110). An evaluation unit (115) is coupled to the at least one sensing path (114) to generate an electrical signal (CTRL) dependent on the optical signal received by the photodiode (111). L'invention concerne un capteur optique (100) comprenant un réseau de pixels, dans lequel chaque pixel comprend une photodiode (111) configurée pour recevoir un signal optique et un nœud flottant (113) couplé à la photodiode (111). Au moins un chemin de détection (114) est couplé de manière capacitive au nœud flottant (113) d'au moins un des pixels (110). Une unité d'évaluation (115) est couplée à l'au moins un chemin de détection (114) pour générer un signal électrique (CTRL) en fonction du signal optique reçu par la photodiode (111).
