Abstract:
An image sensor includes pixels each including: a first transistor and a first switch that are connected in series between a first node configured to receive a first potential and an internal node of the pixel, a gate of the first transistor being coupled with a floating diffusion node of the pixel; a capacitive element, a first terminal of which is connected to the floating diffusion node of the pixel; and several assemblies each including a capacitance connected in series with a second switch coupling the capacitance to the internal node. The sensor also includes a control circuit configured to control, each time a voltage is stored in one of the assemblies of a pixel, an increase of a determined value of a difference in potential between the floating diffusion node and the internal node of the pixel.
