ABSTRACT:
An image sensor that includes a plurality of pixels disposed on a substrate, each pixel includes at least one photosensitive region that collects charges in response to incident light; a charge-to-voltage conversion node for sensing the charge from the at least one photosensitive region and converting the charge to a voltage; an amplifier transistor having a source connected to an output node, having a gate connected to the charge-to-voltage conversion node and having a drain connected to at least a portion of a power supply node; and a reset transistor connecting the output node and the charge-to-voltage conversion node.
