IEEE Circuits and Devices: the Magazine of Electronic and Photonic Systems, 2005
In this article, we provide a basic introduction to CMOS image-sensor technology, design and performance limits and present recent developments and future directions in this area. We also discuss image-sensor operation and describe the most popular CMOS image-sensor architectures. We note the main non-idealities that limit CMOS image sensor performance,

Design, operation and measurement results of a CMOS camera implemented within a SOI wafer are presented. The peak of photodiode quantum efficiency is obtained for the wavelengths of 400-500 nm. In addition, noise measurements of the 1/f noise in P-MOS and N-MOS transistors for analog applications are reported under wide bias conditions ranging from ...

Contactless fluorescence imaging with a CMOS image sensor
2011 IEEE International Symposium of Circuits and Systems (ISCAS), 2011In this work, we utilize a CMOS active pixel sensor in a fluorescence imaging setup. The ability to sense small light intensity changes on top of a large baseline with spatial resolution at the subcellular scale is required in fluorescence imaging.

CMOS image sensors with video compression
Proceedings of 1998 Asia and South Pacific Design Automation Conference, 2002This paper describes CMOS image sensors integrating video compression circuits. The on-sensor compression is particularly useful for the low-power design of moving picture compression hardware, which is demanded especially in the mobile computing and telephony.

CMOS Image Sensor with Watermarking Capabilities
2005 IEEE International Symposium on Circuits and Systems, 2005The problem of authenticity for digital images has been helped by the development of digital watermarking. As an extension of the current state-of-the-art, a CMOS active pixel sensor (APS) imager with built-in watermarking of the output image is presented.

A CMOS Image Sensor for DNA Microarrays
2007 IEEE Custom Integrated Circuits Conference, 2007An image sensor designed with standard 0.18 mum CMOS technology is used to construct a DNA microarray scanner. The detection limit of 4590 fluorophores/mum2 is compared with 4.49 fluorophores/mum2 of a commercial photomultiplier-tube-based microarray scanner.

Image sensors are widely used in today’s consumer electronics and have been integrated with various hand held devices like cell phones. Growing interest has been placed on CMOS image sensor as technology scales and imager sizes approach that of CCDs [79]. This chapter will give a simplified mock 3D example of an active pixel CMOS image sensor.
