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.

Solar Cells, Photodetectors, and Optical Sources from Infrared Colloidal Quantum Dots

TL;DR: In this article, the authors review progress in infrared solar cells, light sensors, and optical sources based on solution-processed materials, including colloidal quantum dots, and provide 4.2% power conversion efficiencies in the infrared, placing them a factor of three away from enabling a doubling in overall solar power conversion efficiency.

Coded rolling shutter photography: Flexible space-time sampling

TL;DR: By controlling the readout timing and the exposure length for each row, the row-wise exposure discrepancy in rolling shutter can be exploited to flexibly sample the 3D space-time volume of scene appearance, and can thus be advantageous for computational photography.

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.
