Abstract
The present description describes an image sensor including an array of pixels arranged inside and on top of a region of a semiconductor substrate electrically insulated from the rest of the substrate by insulating trenches crossing the substrate, each pixel including a photoconversion area and at least two assemblies, each including a memory area and a transfer gate coupling the memory area to the photoconversion area, and a circuit configured to apply, for each pixel and at least during each integration phase, a bias voltage different from ground to a portion of the substrate having the pixel arranged inside and on top of it.
