Abstract
An image sensor having a number of pixel zones delimited by isolation trenches, each pixel zone including a photodiode; a transfer gate associated with each of the pixel zones and arranged to transfer charge from the photodiode to a sensing node; and a read circuit for reading a voltage at one of the sensing nodes, the read circuitry including a number of transistors of which at least one is positioned at least partially over a pixel zone of the pixel zones.
