Abstract
An image sensor array of shared pixel units fabricated by a CMOS technology, wherein each pixel unit includes a plurality of photodiodes and respective transfer transistors and floating drains whose layout constitutes mirror images. The plurality of photodiodes each share a single reset transistor and source follower amplifier transistor wherein the shared floating diode is spaced at the minimum distance from a gate electrode of the source follower transistor as is allowed by the CMOS fabrication technology chosen to manufacture the image sensor array.
