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 pixel includes a photosensitive circuit, a sense node, a first transistor and a first capacitor. A first electrode of the first capacitor is connected to a control terminal of the first transistor. A second electrode of the first capacitor is to a node of application of a first control signal.
