Abstract
An image sensor has an array of pixel blocks, and each pixel block having associated shutter transistors with each coupled to transfer an image signal comprising a charge dependent on light exposure of a selected pixel onto an image storage capacitor of a plurality of image storage capacitors associated with the pixel block, the image storage capacitors of the pixel block configured to be read through a differential amplifier into an analog to digital converter. The differential amplifier of each pixel block receives a second input from a single reset-sampling capacitor associated with the pixel block. The single reset-sampling capacitor is loaded when the pixels of the pixel block are reset.
