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 Sensors and the Quanta Image Sensor
2018 International Conference on Optical MEMS and Nanophotonics (OMN), 2018This paper briefly reviews CMOS image sensor invention and development. The focus of the paper is on a possible successor - the Quanta Image Sensor – a photon-counting image sensor that operates at room temperature without avalanche multiplication. Experimental results with 1Mpixel array devices are described.

A CMOS Sensor for Nano-Imaging
2006 Sixth IEEE Conference on Nanotechnology, 2006We report on the design and measurements of a new direct electron imaging sensor. The active pixel sensor array consists of 512 by 550 pixels, each 5 by 5 μm in size, with a ∼8 μm epitaxial layer, to achieve an effective fill factor of 100%. Spatial resolution of 2.3 μm for a single incident e-has been measured.

The evolution of CMOS image sensors
2013 IEEE Asian Solid-State Circuits Conference (A-SSCC), 2013Previous video cameras were big and heavy. However, CCD image sensors (CCD-ISs) replaced video camera tubes, so that video cameras became smaller and lighter, and video cameras as consumer products were introduced. Moreover, CCD-ISs created a market for digital still cameras and they replaced film cameras because of they were easy to use. However, CMOS
