Abstract
A new CMOS active pixel image sensor is reported. The sensor uses a 2.0 /spl mu/m double-poly, double-metal foundry CMOS process and is realized as a 128/spl times/128 array of 40 /spl mu/m/spl times/40 /spl mu/m pixels. The sensor features TTL compatible voltages, low noise and large dynamic range, and will be useful in machine vision and smart sensor applications. >

Active Pixel Sensors: Are CCD's Dinosaurs?

TL;DR: ActivePixel Sensor (APS) as mentioned in this paper is a detector array technology that has at least one active transistor within the pixel unit cell, which eliminates the need for nearly perfect charge transfer, which makes CCD's radiation'soft' and difficult to use under low light conditions, difficult to integrate with on-chip electronics, difficulty to use at low temperatures, and difficulty to manufacture in non-silicon materials that extend wavelength response.

A random access photodiode array for intelligent image capture

TL;DR: In this article, a chip implementing random scan was designed, fabricated, and tested, which covers the basic requirements for random access and separation between the sampling and reading processes, in this way, a repeated reading of any pixel at any time can take place.

A random access photodiode array for intelligent image capture

TL;DR: A chip implementing random scan was designed, fabricated, and tested and was found to operate functionally, however, the use of a standard process gave rise to the crosstalk phenomenon, which has yet to be overcome.
