It is known that CNN systems are linear for Gabor-type spatial filters. Although it is possible to represent the state equations of the discrete CNN in matrix notation, it is almost impossible to implement the huge state matrix on a digital system without optimization. In this paper some well known linear equation solving methods are optimized for CNN and required computational powers and memories are compared.","PeriodicalId":445822,"journal":{"name":"2007 18th European Conference on Circuit Theory and Design","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122232605","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 N- bittimesN-bit radix-16 serial-parallel multiplier can reduce the number of accumulation cycles of partial products to as much as N/4, and eliminate most of the invertion operations which consume power in a conventional multiplier in generating the partial products. Unlike other high-radix methods, the pre-multiplication in the new algorithm employs a BSD method which requires no extra adder, and thus removes the extra delay for additions which hinders other high-radix algorithms.","PeriodicalId":445822,"journal":{"name":"2007 18th European Conference on Circuit Theory and Design","volume":"117 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129460201","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 mutant-based fault injection techniques are inspired from their classical counterparts [T.A. DeLong et al., 1996] [E. Jenn et al., 1994], and were adapted to the specific features of quantum computation, including the available error models [J. P. Hayes et al., 2004] [E. Knill et al., 1997]. The HDLs were employed in order to perform fault injection, due to their capacity of behavioral and structural circuit description, as well as their hierarchical features. Besides providing a much realistic description, the experimental simulated fault injection campaigns provide quantitative means for quantum fault tolerance assessment.","PeriodicalId":445822,"journal":{"name":"2007 18th European Conference on Circuit Theory and Design","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126992485","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 paper the tracking limits for a linear-surface sliding-mode controlled ideal buck converter are addressed for different representative cases, namely, for a single tone, two tones, multiple tone, and a generalization to an arbitrary wideband signal. Analytical design-oriented equations are matched with simulations both for synthetic single-tone and arbitrary wideband noise signal as well as for the envelope signal corresponding to the EDGE standard in an envelope elimination and restoration technique polar RF transmitter architecture.","PeriodicalId":445822,"journal":{"name":"2007 18th European Conference on Circuit Theory and Design","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123899027","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}

Regarding technology, the modulator, which uses any active inductor, is able to operate at high frequency and provides digital output with suitable phase noise.

The approach is based on determination of the variations of circuit functions with use of higher order sensitivity coefficients. Knowing values of sensitivity coefficients one can formulate multivariate polynomial equations. The solution of test equations with respect to element's deviations results in fault identification. This task can be realized by using Grobner bases to transform a nonlinear equation into triangular form. It is solved by successive computation of the univariate polynomial equation and back substitution. Solution of the polynomial equation is treated as the eigenvalue problem of companion matrix by QR algorithm. Numerical results are presented to clarify method and prove its efficiency.","PeriodicalId":445822,"journal":{"name":"2007 18th European Conference on Circuit Theory and Design","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116666308","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}
