Abstract
A pixel including a first node, a second node configured to receive a first DC potential, and a plurality of acquisition channels each including: a photodiode adapted to detect radiation in a first wavelength range; a capacitive element coupling the photodiode to the first node; and a resistive element coupling a first terminal of the photodiode to the second node.

A pixel comprising a first node, a second node configured to receive a first DC potential, and a plurality of acquisition channels each comprising:
- a photodiode adapted to detect radiation in a first wavelength range;
- a capacitive element coupling the photodiode to the first node;
- and
- a resistive element coupling a first terminal of the photodiode to the second node,
- wherein the pixel further comprises:
- a switch coupling the first node to a node configured to receive a second DC potential;
- and
- a control circuit configured to control the switch to the off state during an acquisition phase so that the first node is floating.
