Reading is a hobby to open the knowledge windows. Besides, it can provide the inspiration and spirit to face this life. By this way, concomitant with the technology development, many companies serve the e-book or book in soft file. The system of this book of course will be much easier. No worry to forget bringing the a biologically inspired cmos image sensor book. You can open the device and ge...

This paper presents noise characterization of a CMOS 0.6-μm image sensors system. The integrated readout circuit adaptability allows measuring the photocurrent magnitude of each pixel in charge integration mode or in transimpedance mode. In order to find the minimum detectable signal of this system and to identify the main dominant noise sources, an accurate noise analysis is performed under da...

A CMOS image sensor ADC using delta-sigma modulation is presented and discussed. Experimental results from a test chip are presented. The experimental results show that the proposed ADC has several benefits over the use of pipeline ADCs including noise reduction, fast design times, ease with which to maximize ADC output based on a varying input range, and simple symmetric analog routing for lar...

This article describes a 4 / 16 Mpixel CMOS image sensor with 106 dB efficiency snapshot electronic shutter and 62 dB dynamic range within +/3 % linearity. It is monolithic, front side illuminated and processed on plain 0.35 μm process with stitching. This sensor could be an interesting alternative to power consuming TDI CCD sensors in LEO orbit configuration.

We have developed a 16Mpixel 3D stacked global-shutter CMOS image sensor with pixel level interconnections using 4 million micro bumps. The four photodiodes in the unit pixel circuit on the top substrate share one micro-bump interconnection at a 7.6μm pitch. Each signal of the photodiodes is transferred to the corresponding storage node on the bottom substrate via the interconnection to achieve...

The downscaling of CMOS technology gives rise to a myriad of nanoscale effects. At the same time, power density and thus heat generation increases. The aim of this paper is to evaluate the feasibility of both analogue and digital temperature sensors in nanoscale CMOS using the Berkeley Predictive Technology Model (BPTM) for 65nm. For the oscillator-based digital sensor presented, a sensitivity ...

This paper describes an image acquisition and a processing system based on a new co-processor architecture designed for CMOS sensor imaging. The system exploits the full potential CMOS selective access imaging technology because the co-processor unit is integrated into the image acquisition loop. The acquisition and co-processing architecture is compatible with the majority of CMOS sensors. It ...

In this paper, we propose an embedded system for extracting assigned objects from an RGB image taken by the low level CMOS lens, which is installed in the embedded system. The system uses ARM9 PXA270 as the development platform and combines image preprocessing, image enhancement technology and the fuzzy calculating method to extract the assign objects. The peripheral hardware of ARM9 PXA270 are...
