Abstract: In some embodiments, an imaging device includes a pixel array. At least one of the pixels includes a photodiode that can generate charges, and a select transistor that receives the charges in its bulk. When the select transistor is selected, a pixel current through it may depend on a number of the received charges, thus evidencing how much light it detected. A reset transistor may reset the voltage of the bulk.
