Extended One-Dimensional Analysis to Effectively Derive Quantum Efficiency of Various CMOS Photodiodes
TL;DR: In this paper, an extended 1-D analysis to derive quantum efficiency of various commonly used CMOS photodiodes is proposed, where the minority carrier and current densities are continuous across the interface between two layers with the same dopant type.

Single-chip camera modules for mosaic image sensor
TL;DR: A method is described in which the number and sizes of pixel clusters above an intensity threshold are determined using a novel 'object positioning algorithm' architecture, which identifies significant events or objects in the scene before the camera's data are transmitted over the bus, thereby reducing the effective bandwidth.

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.
