CMOS image sensors for sensor networks
Analog Integrated Circuits and Signal Processing, 2006We report on two generations of CMOS image sensors with digital output fabricated in a 0.6 ?m CMOS process. The imagers embed an ALOHA MAC interface for unfettered self-timed pixel read-out targeted to energy-aware sensor network applications. Collision on the output is monitored using contention detector circuits.

On-Chip Digital Temperature Sensor for CMOS Image Sensor
2018 International Conference on Biomedical Engineering and Applications (ICBEA), 2018The Digital Temperature Sensors relies on two main parts: temperature sensor with analogue output and analogue-to-digital converter. The analogue temperature sensor architecture developed in this work consists on having a circuit with MOSFETs producing an output voltage proportional to absolute temperature the most linear possible. This voltage is then

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.

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.
