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 Vision Sensor for Background Subtraction
2020 IEEE International Symposium on Circuits and Systems (ISCAS), 2020Background subtraction is one of the first steps in many video processing algorithms. Thus, a real-time processing with low power consumption is convenient for different applications where power hungry devices with high computational capabilities can not be deployed.

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.

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 stress sensors on [100] silicon
IEEE Journal of Solid-State Circuits, 2000CMOS analog stress sensor circuits based upon the piezoresistive behavior of MOSFET's are presented. On the [100] surface, these circuits provide temperature-compensated outputs that are proportional to the in-plane normal stress difference (/spl sigma/(11)'-/spl sigma//sub 22/') and the in-plane shear stress /spl sigma//sub 22/'.
