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

TL;DR: In this article, a CMOS pixel test structure able to withstand doses in excess of 1.5 GHz was presented, and the point spread function measured with 300 keV electrons was (8.1 ± 1.6 ) μ m for 10 μ m pixel and (10.9 ± 2.3 ) μm for 20 μ m pixels, respectively, which agrees well with the values of 8.4 and 10.5 μ m predicted by simulation.

TL;DR: In this article, the feasibility of a new implementation of CMOS monolithic active pixel sensors (MAPS) for applications to charged particle tracking is studied. But the authors focus on the front-end of the front end of the system, which relies upon a charge sensitive amplifier (CSA), embedded in the elementary pixel cell.

Analysis of Total Dose-Induced Dark Current in CMOS Image Sensors From Interface State and Trapped Charge Density Measurements
TL;DR: In this article, the origin of total ionizing dose induced dark current in CMOS image sensors was investigated by comparing dark current measurements to interface state density and trapped charge density measurements, and it was shown that the radiation induced trapped charge extends the space charge region at the oxide interface, leading to an enhancement of interface state SRH generation current.

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.
