A Deep Sub-Electron Temporal Noise CMOS Image Sensor with Adjustable sinc-type Filter to Achieve Photon Counting Capability

This letter introduces a Gm-cell-based CMOS image sensor (CIS) achieving deep subelectron noise performance. The CIS presents a new compensation block and low-noise current source to improve the performance of the Gm pixel. Furthermore, an optional first-order IIR filter is implemented to improve the output swing. The conversion gain, full...

A CMOS-Imager-Pixel-Based Temperature Sensor for Dark Current Compensation

This brief proposes employing each of the classical 4 transistor (4T) pinned photodiode (PPD) CMOS image sensor (CIS) pixels, for both imaging and temperature measurement, intended for compensating the CISs' dark current, and dark signal non-uniformity (DSNU). The proposed temperature sensors rely on the thermal behavior of MOSFETs working in...

LogChunks: A Data Set for Build Log Analysis

Build logs are textual by-products that a software build process creates, often as part of its Continuous Integration (CI) pipeline. Build logs are a paramount source of information for developers when debugging into and understanding a build failure. Recently, attempts to partly automate this time-consuming, purely manual activity have come up,...

Compensation for Process and Temperature Dependency in a CMOS Image Sensor

This paper analyzes and compensates for process and temperature dependency among a (Complementary Metal Oxide Semiconductor) CMOS image sensor (CIS) array. Both the analysis and compensation are supported with experimental results on the CIS’s dark current, dark signal non-uniformity (DSNU), and conversion gain (CG). To model and to...

Exploring the driving factors of construction industrialization development in China

Construction industrialization (CI) has been adopted worldwide because of its potential benefits. However, current research shows the incentives for adopting CI may differ in different regions. While the promotion of CI in China is still at the initial stage, a systematical analysis of the driving factors would help decision makers get a...

Distributional theory for the DIA method

The DIA method for the detection, identification and adaptation of model misspecifications combines estimation with testing. The aim of the present contribution is to introduce a unifying framework for the rigorous capture of this combination. By using a canonical model formulation and a partitioning of misclosure space, we show that the...

Does RAIM with correct exclusion produce unbiased positions?

As the navigation solution of exclusion-based RAIM follows from a combination of least-squares estimation and a statistically based exclusion-process, the computation of the integrity of the navigation solution has to take the propagated uncertainty of the combined estimation-testing procedure into account. In this contribution, we analyse,...

Characterization of metals for Cochlear Implants

The need for Cochlear Implants (CI's) with improved functionality and quality requires new techniques to be used to manufacture the electrode array. Titanium nitride (TiN) is one of the contenders for use as metal in the future CI's, but its characteristics need to be verified, measured and tested. A metal should comply to certain requirements...

An autonomous low power high resolution micro-digital sun sensor

Micro-Digital Sun Sensor (?DSS) is a sun detector which senses the respective angle between a satellite and the sun. It is composed of a solar cell power supply, a RF communication block and a CMOS Image Sensor (CIS) chip, which is called APS+. The paper describes the implementation of a prototype of the ?DSS APS+ processed in a standard 0.18?m...

Measuring Innovation and the Propensity to Patent

Patents are often taken as an indicator to measure innovativeness, because they are a lot easier to obtain than most others. There is a complication though, which is that patents are not a direct measure of innovativeness: the fit between patents and innovativeness is biased by differing propensities to patent. The propensity to patent was...

A CMOS Image Sensor With In-Pixel Buried-Channel Source Follower and Optimized Row Selector

This paper presents a CMOS imager sensor with pinned-photodiode 4T active pixels which use in-pixel buried-channel source followers (SFs) and optimized row selectors. The test sensor has been fabricated in a 0.18-mum CMOS process. The sensor characterization was carried out successfully, and the results show that, compared with a regular imager...

Negative Offset Operation of Four-Transistor CMOS Image Pixels for Increased Well Capacity and Suppressed Dark Current

This letter presents an electrical method to reduce dark current as well as increase well capacity of four-transistor pixels in a CMOS image sensor, utilizing a small negative offset voltage to the gate of the transfer (TX) transistor particularly only when the TX transistor is off. As a result, using a commercial pixel in a 0.18 ?m CMOS process...
