Abstract: An active cell for a photosensitive sensor that includes photosensitive diode in which the transistors of the cell are implemented using CMOS technology. The cell operates with an exposure phase in which the quantity of light impinging on the cell is detected followed by a scanning phase during which the luminance information caused by the impinging light is extracted from the cell. The cell is arranged in such a way to virtually completely isolate the charge accumulation node from the remainder of the cell after the exposure phase to eliminate stray accumulation of charge carriers.
