The method, based on shaping, relies on the optimization of the shape of the distributed domain in order to avoid excessive current stream lines crowding. Consequently hot spots are practically absent improving thus considerably the thermal stability of distributed attenuators as well as their overdriving endurance. A design example for proving the validity of this approach is presented in order to emphasize the advantages of the proposed method.","PeriodicalId":6406,"journal":{"name":"2008 IEEE International Conference on Semiconductor Electronics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2008-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78722144","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}

We have studied the effect of K-fluorescence reabsorption coupled with anomalous scattering on the performance of Se in protein crystallography detectors. Anomalous scattering is used as a method of phase calculation in crystallography. For occurrence of anomalous scattering, incident X-ray energy is made equal to the K-edge energy of Se. Our study indicates that significant K--fluorescence escape and reabsorption occurs at K-edge energy which degrades spatial resolution, sensitivity, and signal-to-noise ratio of the detector.","PeriodicalId":6406,"journal":{"name":"2008 IEEE International Conference on Semiconductor Electronics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2008-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75027079","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 proposed architecture is generic as: (i) it takes into account all delay variation sources; (ii) applies solutions at design, test, and run time; (iii) and can be used as a template for all kind of systems, e.g., uni-processor, multi-processor. The Casta DIVA approach is introspective, that is, the system locally observes its own performance and adapts locally to the actual measured delay, by the use of local agents. To achieve global control too, the local agents are placed in a 3-level hierarchy. To reduce the extra hardware cost and to facilitate easy integration with existing design technologies we propose to utilize the JTAG boundary scan as test and communication infrastructure.","PeriodicalId":6406,"journal":{"name":"2008 IEEE International Conference on Semiconductor Electronics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2008-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81190893","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}

An original technique for linearizing the current-voltage characteristic of the active resistor will be proposed, based on the utilization of a MOS differential amplifier, whose transfer characteristic is linearized using an original biasing. The controllability of the active resistor circuit is excellent, being possible to modify the circuit equivalent resistance by changing the value of the biasing current.
