1. A pixel, comprising:
a photosensitive circuit;
a sense node; and
a first transistor having a control terminal connected to the sense node and having a first conduction terminal connected to a node of application of a first control signal;
wherein a second conduction terminal of the first transistor is connected to an inner node, and wherein there is no bias current delivered to the second conduction terminal of the first transistor by any transistor connected to the inner node; and
circuitry configured, for each operation to store a potential level of the sense node, to apply the first control signal as a ramp signal.
