Abstract
An image sensor array. The image sensor array includes a substrate. An array of photo diode sensors are electrically interconnected to the substrate. The photo diode sensors conduct charge at a rate proportional to the intensity of light received by the photo diode sensors. A ring of guard diodes are located around the periphery of the array of photo diode sensors. Each guard diode has a guard diode anode connected to a predetermined guard anode voltage and a guard diode cathode connected to a static guard cathode voltage.
