As the technology has moved toward to the lower voltage and higher gate density, the need to monitor the silicon temperature and supply voltage to prevent damage has become critical. Especially, in those systems with large power consumption with sudden power failure that may damage the system and be expense to be repaired. Therefore, it is better to have the monitor chips inside the system to prevent the failure. The /spl Sigma/-/spl Delta/ converter has the design advantages of a simple analog circuit and smaller die digital cell to achieve the low cost for monitoring.","PeriodicalId":437349,"journal":{"name":"Proceedings of the 43rd IEEE Midwest Symposium on Circuits and Systems (Cat.No.CH37144)","volume":"162 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133972552","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}

For example, in virtual surgery and teleoperation of satellites and robots. On the other hand, Internet is the great world net of heterogeneous computers that is in constant evolution since its creation, in the 60's. New technologies appear for the \"Net\" everyday. One of the largest revolutions in this area is the Java language. Thus, it is possible to join Teleoperation and Internet in order to control a robot from any computer linked to the global net. This work presents a quite simple interface for robot teleoperation: the keyboard keys move the robot while images generated by the camera onboard the robot are sent to the navigator.","PeriodicalId":437349,"journal":{"name":"Proceedings of the 43rd IEEE Midwest Symposium on Circuits and Systems (Cat.No.CH37144)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131824394","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}

This technique is based on replacing the constituent quantizer by a uniformly distributed additive white noise source and a variable gain element, assuming the following conditions are satisfied: a) the quantizer input signal and quantization error are uncorrelated, b) the quantizer input signal is Gaussian distributed, and c) the quantization noise is white. It is shown that the statistical estimation technique is quite accurate for /spl Sigma/-/spl Delta/ A/D converters with small noise power gains, but that the accuracy tends to decrease for A/D converters having larger noise power gains. It is further shown that this reduction in accuracy stems from the fact that the assumptions listed under a), b), and c) are not exactly satisfied. It is finally shown that the probability density function of the input signal to the quantizer may be modelled more accurately using the Gram-Charlier series.","PeriodicalId":437349,"journal":{"name":"Proceedings of the 43rd IEEE Midwest Symposium on Circuits and Systems (Cat.No.CH37144)","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134317370","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}

In this article, we show that the bond graph representation is a good candidate for such a functional representation because its formalism deletes a piece of information which is useless for analyzing the circuit's functioning. However, the existing algorithms which transform a circuit into a bond graph are not fully adapted to this formalism. A more suitable algorithm is proposed, based on the Tutte decomposition of graphs. This algorithm associates a unique bond graph with a given circuit and it formalizes the \"inspection method\" suggested by Karnopp [1975]. With this new algorithm, the gap between the bond graph representation and the functional representation is reduced.","PeriodicalId":437349,"journal":{"name":"Proceedings of the 43rd IEEE Midwest Symposium on Circuits and Systems (Cat.No.CH37144)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123391480","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}
