This book was released on 1996 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: La cr2ation d'outils CAO specifiques pour l'automatisation du dessin des masques de circuits integres analogiques est devenue un enjeu important, particulierement dans le domaine des telecommunications, afin de pouvoir realiser rapidement des circuits mixtes comportant a la fois des parties logiques et analogiques. Ces outils specifiques doivent minimiser la surface totale occupee tout en assurant le bon fonctionnement final du circuit. Cette these presente donc deux logiciels originaux qui sont partie integrante d'un systeme complet de dessin des masques automatique pour les circuits integres analogiques. Le premier permet de dessiner des transistors mos dont la forme globale peut etre definie par l'utilisateur de maniere a ce qu'ils s'inserent mieux dans l'ensemble du circuit. Le second est un routeur analogique qui permet de realiser les interconnexions entre tous les composants du circuit tout en prenant en compte de maniere globale tous les elements parasites introduits (capacites et resistances). Ces deux outils ont permis l'introduction de nouvelles methodes de dessin des masques et ont ete completement integres dans un environnement de cao afin de donner un maximum de controle a l'utilisateur.

This book was released on 2007 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: La realisation des circuits integres analogiques a hautes performances souffre de difficultes principalement dues a la reduction de la tension d'alimentation et a la reduction de la consommation, qui sont conduites par la proliferation des systemes portables alimentes par des batteries, mais patit aussi du manque d'outils de c.a.o permettant d'automatiser la phase de layout qui est assez laborieuse et prend beaucoup de temps. Cette these se situe dans ce contexte. Elle traite de deux domaines assez distincts mais complementaires, a savoir la conception de circuits integres analogiques a faible tension d'alimentation, et la generation automatique (ou assistee) du layout de ces circuits a l'aide d'algorithmes et de logiciels appropries. L'aboutissement de cette these est, premierement, la creation d'une nouvelle methode de conception des circuits integres analogiques, plus precisement la generation d'une technique de conception de nouvelle structure, plus adaptee aux basses tensions d'alimentation et aux faibles consommations, deuxiemement, notre contribution a l'automatisation de la phase du layout des circuits integres analogiques, a savoir l'etude detaillee des contraintes analogiques a prendre en compte dans tout outil d'automatisation du layout (generateur, placeur, routeur, compacteur), ainsi que notre participation au developpement de chrvan (outils d'automatisation des masques des circuits integres analogiques et mixtes, developpes au cnet grenoble) en aidant a sa mise au point, en l'utilisant, en proposant des ameliorations, et surtout en consacrant tous nos efforts a developpe un algorithme de placement des cellules analogiques qui prend en compte toutes ces contraintes analogiques.

Download or read book Numerical Methods for Partial Differential Equations written by Sandip Mazumder and published by Academic Press. This book was released on 2015-12-01 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: Numerical Methods for Partial Differential Equations: Finite Difference and Finite Volume Methods focuses on two popular deterministic methods for solving partial differential equations (PDEs), namely finite difference and finite volume methods. The solution of PDEs can be very challenging, depending on the type of equation, the number of independent variables, the boundary, and initial conditions, and other factors. These two methods have been traditionally used to solve problems involving fluid flow. For practical reasons, the finite element method, used more often for solving problems in solid mechanics, and covered extensively in various other texts, has been excluded. The book is intended for beginning graduate students and early career professionals, although advanced undergraduate students may find it equally useful. The material is meant to serve as a prerequisite for students who might go on to take additional courses in computational mechanics, computational fluid dynamics, or computational electromagnetics. The notations, language, and technical jargon used in the book can be easily understood by scientists and engineers who may not have had graduate-level applied mathematics or computer science courses. - Presents one of the few available resources that comprehensively describes and demonstrates the finite volume method for unstructured mesh used frequently by practicing code developers in industry - Includes step-by-step algorithms and code snippets in each chapter that enables the reader to make the transition from equations on the page to working codes - Includes 51 worked out examples that comprehensively demonstrate important mathematical steps, algorithms, and coding practices required to numerically solve PDEs, as well as how to interpret the results from both physical and mathematic perspectives

Download or read book Programming for Electrical Engineers written by James C. Squire and published by Academic Press. This book was released on 2020-07-08 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: Programming for Electrical Engineers: MATLAB and Spice introduces beginning engineering students to programming in Matlab and Spice through engaged, problem-based learning and dedicated electrical and computer engineering content. The book draws its problems and examples specifically from electrical and computer engineering, covering such topics as circuit analysis, signal processing, and filter design. It teaches relevant computational techniques in the context of solving common problems in electrical and computer engineering, including mesh and nodal analysis, Fourier transforms, and phasor analysis. Programming for Electrical Engineers: MATLAB and Spice is unique among MATLAB textbooks for its dual focus on introductory-level learning and discipline-specific content in electrical and computer engineering. No other textbook on the market currently targets this audience with the same attention to discipline-specific content and engaged learning practices. Although it is primarily an introduction to programming in MATLAB, the book also has a chapter on circuit simulation using Spice, and it includes materials required by ABET Accreditation reviews, such as information on ethics, professional development, and lifelong learning. - Discipline-specific: Introduces Electrical and Computer Engineering-specific topics, such as phasor analysis and complex exponentials, that are not covered in generic engineering Matlab texts - Accessible: Pedagogically appropriate for freshmen and sophomores with little or no prior programming experience - Scaffolded content: Addresses both script and functions but emphasizes the use of functions since scripts with non-scoped variables are less-commonly encountered after introductory courses - Problem-centric: Introduces MATLAB commands as needed to solve progressively more complex EE/ECE-specific problems, and includes over 100 embedded, in-chapter questions to check comprehension in stages and support active learning exercises in the classroom - Enrichment callouts: "Pro Tip" callouts cover common ABET topics, such as ethics and professional development, and "Digging Deeper" callouts provide optional, more detailed material for interested students

Download or read book Quantum Communications and Cryptography written by Alexander V. Sergienko and published by CRC Press. This book was released on 2018-10-03 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: All current methods of secure communication such as public-key cryptography can eventually be broken by faster computing. At the interface of physics and computer science lies a powerful solution for secure communications: quantum cryptography. Because eavesdropping changes the physical nature of the information, users in a quantum exchange can easily detect eavesdroppers. This allows for totally secure random key distribution, a central requirement for use of the one-time pad. Since the one-time pad is theoretically proven to be undecipherable, quantum cryptography is the key to perfect secrecy. Quantum Communications and Cryptography is the first comprehensive review of the past, present, and potential developments in this dynamic field. Leading expert contributors from around the world discuss the scientific foundations, experimental and theoretical developments, and cutting-edge technical and engineering advances in quantum communications and cryptography. The book describes the engineering principles and practical implementations in a real-world metropolitan network as well as physical principles and experimental results of such technologies as entanglement swapping and quantum teleportation. It also offers the first detailed treatment of quantum information processing with continuous variables. Technologies include both free-space and fiber-based communications systems along with the necessary protocols and information processing approaches. Bridging the gap between physics and engineering, Quantum Communications and Cryptography supplies a springboard for further developments and breakthroughs in this rapidly growing area.
