Abstract: A method of making an image sensor, the method includes the steps of providing a plurality of pixels each with a photodetector; providing an amplifier that is shared between the plurality of photodetectors; providing a transfer gate associated with each photodetector; providing a charge-to-voltage conversion region that is shared between the plurality of photodetectors; determining a capacitance between each transfer gate and the charge-to-voltage conversion region; and modifying the capacitance to be substantially the same by altering a physical structure within one or more pixels.

Abstract: An image sensor includes a plurality of pixels, at least two pixels each having a photodetector; a charge-to-voltage conversion region; an input to an amplifier; and a switch for selectively connecting the charge-to-voltage conversion regions.

Abstract: An image sensor includes a unit cell having a plurality of pixels; the unit cell having a plurality of photodetectors having two or more subsets in which each subset has a physical shape which is different than the other subset; and light-shielding layers that create an aperture associated with each photodetector; wherein the light-shielding layers are positioned so that any physical translation of the light-shielding layers with respect to the photodetectors creates a substantially equal change in optical response of the photodetectors.

Abstract: An image sensor includes a plurality of photodetectors arranged in an array; and a plurality of transistors that are functionally shared by the photodetectors, wherein a distance of each photodetector to an adjacent transistor is substantially the same.

Abstract: An image sensor includes a two-dimensional array of pixels having a photodetector for collecting charge in response to incident light; a storage region adjacent the photodetector that receives the charge from the photodetector; a sense node adjacent the storage region that receives the charge from the storage region and converts the charge to a voltage signal; and an input to an amplifier for sensing the voltage signal from the sense node.
