CMOS image sensors: electronic camera-on-a-chip
TLDR
In this article, the requirements for CMOS image sensors and their historical development, CMOS devices and circuits for pixels, analog signal chain, and on-chip analog-to-digital conversion are reviewed and discussed.Abstract:
CMOS active pixel sensors (APS) have performance competitive with charge-coupled device (CCD) technology, and offer advantages in on-chip functionality, system power reduction, cost, and miniaturization. This paper discusses the requirements for CMOS image sensors and their historical development, CMOS devices and circuits for pixels, analog signal chain, and on-chip analog-to-digital conversion are reviewed and discussed.read more

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.
