Abstract
An image sensor includes an array of pixels inside and on top of a substrate. A control circuit is configured to apply voltage potentials to the substrate. During a first phase, the control circuit applies a ground potential to the substrate. During a second phase, the control circuit applies a potential positive with respect to the ground potential to the substrate.
