Adaptivity is useful in applications where the statistics of the source are either not known a priori or will change over time. The proposed method first determines two quantizer cells and the corresponding output levels such that the distortion is minimized over all possible two-level quantizers. Then the cell with the largest empirical distortion is split into two cells in such a way that the empirical distortion is minimized over all possible splits. Each time a split is made, the number of output levels increases by one until the target number of cells is reached. Finally, the resultant quantizer serves as a good initial starting point for running the Lloyd-Max Algorithm in order to reach global optimality. Experimental results show that this new designed quantizer outperforms that obtained by the Lloyd-Max method started with an arbitrary initial point in terms of Mean Square Error (MSE). Moreover, the proposed method converges more rapidly than the Lloyd-Max one. Our method adapts itself to the histogram of the data without creating any empty output range. This feature improves the robustness of the design method.","PeriodicalId":442381,"journal":{"name":"2010 XIth International Workshop on Symbolic and Numerical Methods, Modeling and Applications to Circuit Design (SM2ACD)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131960784","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}

Solving the extraction problem, in the particular case of a linear circuit, can be reduced to the math problem of determining the solutions of a system of polynomial equations. During resolution, classical mathematical algorithms used in the symbolic computing phase could generate during execution symbolic polynomials of size that could increase too fast (by a double exponential law) with the size of the input polynomials (thus making the symbolic computation useless), but in the case of specialized algorithms the size of intermediate polynomials could grow much slower (only by a polynomial law). An insight of the state of art of computational algebra can identify the main algorithms having good performance in terms of computational complexity to be used for symbolic variables elimination between the equations of a polynomial system. This paper analyzes, using a particular circuit, the performance of existing implementations for CAD math systems, which use symbolic methods based on different mathematical approaches, and compares the performances of these programs.","PeriodicalId":442381,"journal":{"name":"2010 XIth International Workshop on Symbolic and Numerical Methods, Modeling and Applications to Circuit Design (SM2ACD)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129792324","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 would ensure that the circuit will function as per specifications after fabrication even with impact of statistical variations in nanometer regimes. The methodology necessitates the evaluation of performance metrics of an analog circuit for different sizing instances of the transistors. Circuit simulation for performance evaluation is very time consuming and is seldom a choice while sizing a circuit for a chosen topology. The complexity of sizing methodology increases with the need to consider effects of variations in process and environment parameters. We employ macromodeling approach for analog circuits based on support vector machine (SVM), which enables efficient evaluation of performance of such circuits during sizing and yield optimization loops. The objective to improve evaluation efficiency has been the motivation behind efforts to develop performance macromodels, which should be as accurate as SPICE and at the same time have shorter evaluation time for use in the sizing of analog circuits, where they are used as substitutes for full circuit simulation during circuit sizing (synthesis). Process variability aware SVM macromodels are used in the multiobjective multivariate sizing method which is also yield optimal. Post design centering, the sized circuits will be able to provide functions as per specifications upon fabrication. Its application as process variability analysis tool is illustrated on two stage op amp and a voltage controlled oscillator using 90 nm BSIM4 models of transistors.","PeriodicalId":442381,"journal":{"name":"2010 XIth International Workshop on Symbolic and Numerical Methods, Modeling and Applications to Circuit Design (SM2ACD)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131982480","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}
