Abstract
An imaging array having a plurality of pixels is disclosed. Each pixel includes a photodetector that converts light to charge, a floating diffusion node, a first amplification stage connected to the floating diffusion node, and a select gate that connects the pixel to a second amplification stage. The first and second amplification stages form a current mirror. The first amplification stage includes a buried channel device. In one aspect of the present invention, the current minor has an overall voltage gain of between 0.9 and 1.1. In another aspect of the invention, the second amplification stage is shared by a plurality of pixels.
