In the last decade, active pixel sensors (APS), which are fabricated in a commonly used CMOS process, enabled the design of image sensors with integrated \"intelligence\". Current state of the art CMOS imagers allow integration of all functions required for timing, exposure control, color processing, image enhancement, image compression and ADC on the same die. Moreover, systems with wide dynamic range, motion detection and non-standard readout can be designed. CMOS imagers also offer significant advantages in terms of low-power, low-voltage and monolithic integration, rivaling traditional charge coupled devices (CCD). This paper covers state of the art CMOS imager systems and design challenges with the advanced CMOS technologies available. Specifically, ways to improve power consumption in such \"smart\" sensors, required to cope with the current demand for portable systems are reviewed. In addition, pixel optimization is revisited as more advanced processes are used and pixel pitch is reduced.","PeriodicalId":38467,"journal":{"name":"Giornale di Storia Costituzionale","volume":"1 1","pages":"240-"},"PeriodicalIF":0.0,"publicationDate":"2004-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78187617","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The data-path is based on a flexible, universal, and regular component that allows one to optimally exploiting both inter- and intra-component chaining of operations. The component is implemented as a combinational circuit and the steering logic existing inside the component allows one to easily realizing any desirable complex hardware unit - called a template - so that the data-path's performance benefits from the chaining of operations. Due to the universal structure of the component, the synthesis of an application is accomplished by unsophisticated, yet efficient, algorithms. An average reduction of 20% in latency is achieved when a comparison with a template-based data-path is performed.","PeriodicalId":38467,"journal":{"name":"Giornale di Storia Costituzionale","volume":"27 1","pages":"495-498"},"PeriodicalIF":0.0,"publicationDate":"2004-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73746048","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The presented algorithm is very simple and efficient, and it can be used for purposes of protection, control and measurement in EPS, as well. The algorithm is based on mathematically simple expressions, which do not require high processing power, so it is convenient for single chip applications. This algorithm is considered with high and low sampling rate, and proper pre-processing of signal in integrated data acquisition and control systems in EPS is proposed. It is shown that the achieved accuracy can satisfy requests of the intended application.","PeriodicalId":38467,"journal":{"name":"Giornale di Storia Costituzionale","volume":"3 1","pages":"451-454"},"PeriodicalIF":0.0,"publicationDate":"2004-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81699154","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
