An integrated circuit includes at least one photodiode associated with a read transistor. The photodiode is formed from a stack of three semiconductor layers comprising a buried layer, an floating substrate layer and an upper layer. The drain region and/or the source region of the transistor are incorporated within the upper layer. The buried layer is electrically isolated from the upper layer so as to allow the buried layer to be biased independently of the upper layer.
