Abstract: An indirect time-of-flight (iTOF) includes a pixel with a photoconversion area, a readout circuit and at least two circuit sets. Each circuit set includes: a capacitive element connected to a first node of the circuit set; a controllable charge transfer device connected between a first electrode of the photoconversion area and the first node; and a first transistor having a gate connected to the first node, a source connected to the readout circuit and a drain configured to receive a bias potential. The capacitive element is configured to store a voltage in response to charges generated by the photoconversion area.

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.

Abstract: A sensor includes pixels each including: a first transistor and a first switch in series between a first node and an internal node of the pixel, a gate of the first transistor being coupled to a second node; a capacitive element, a first terminal of which is connected to the second node; and a plurality of assemblies each including a capacitance in series with a second switch coupled to the internal node. The sensor includes a circuit configured to control, each time a voltage is stored in one of the assemblies, the interruption of a current between the first node and the internal node: by switching a first potential applied to a second terminal of the capacitive element; or by opening the first switch.

Abstract: A photosensitive sensor is capable of operating in a global shutter mode and in a rolling shutter mode. The sensor includes at least one pixel with a photosensitive region configured to photogenerate charges. A first transfer gate is configured to transfer photogenerated charges from the photosensitive region to a transfer node. A source-follower transistor is configured to transmit a reading signal to a read node, in the global shutter mode, in a manner controlled by a potential of the photogenerated charges on the transfer node. A second transfer gate is configured to transfer the photogenerated charges from the photosensitive region to the read node in the rolling shutter mode.

Abstract: In an embodiment a method for measuring ambient light includes successively synchronizing optical signal acquisition phases with extinction phases of a disruptive light source, wherein the disruptive light source periodically provides illumination phases and the extinction phases, accumulating, in each acquisition phase, photo-generated charges by at least one photosensitive pixel comprising a pinned photodiode, wherein an area of the pinned photodiode is less than or equal to 1/10 of an area of the at least one photosensitive pixel, transferring, for each pixel, the accumulated photo-generated charges to a sensing node, converting, for each pixel, the transferred charges to a voltage at a voltage node and converting, for each pixel, the transferred charges to a digital number
