This book was released on 2010 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Avec l'apparition d'applications grand-public, comme le Wireless-HD, les fréquences millimétriques nécessitent l'utilisation de technologies CMOS faible coût. Cependant, avant d'être commercialisés, les transmetteurs mmW doivent être suffisamment résistants notamment à la désadaptation d'impédance entre l'amplificateur de puissance (AP) et l'antenne qui peut résulter d'un obstacle dans le champ proche de l'antenne. Une telle désadaptation d'impédance se traduit par l'apparition d'ondes stationnaires qui peuvent engendrer des dommages irrémédiables sur l'AP. Cette thèse propose une architecture innovante de régulation qui vise à protéger l'AP de telles dégradations tout en optimisant ses performances. La désadaptation d'impédance peut être évaluée en intégrant plusieurs détecteurs de puissance entre l'AP et l'antenne. Une boucle de régulation numérique peut ensuite établir une stratégie d'optimisation des performances de l'AP. Cette thèse s'intéresse particulièrement aux circuits de détection de puissance qui captent la désadaptation d'impédance de l'antenne. Réalisé en technologie CMOS 65nm de STMicroelectronics, le détecteur de puissance présente 25dB de dynamique à 60GHz et est capable de détecter jusqu'à 3 :1 de TOS. Ces détecteurs de puissance ont ensuite été intégrés dans un second circuit avec un AP et des convertisseurs (CAN & CNA). Une boucle de régulation agissant sur le gain de l'AP permet ainsi de garder une puissance de sortie constante quelle que soit l'impédance d'antenne tandis qu'une seconde boucle protège l'AP de la destruction. Cette thèse couvre également deux projets développés en parallèle de l'architecture de régulation de TOS. D'abord est proposée une nouvelle architecture de convertisseur analogique numérique logarithmique, basée sur l'architecture d'amplificateur logarithmique à compression progressive. Ensuite, une co-simulation sous ADS d'un AP RF/mmW avec sa boucle de régulation numérique permet de simuler l'AP à TOS régulé.

This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cette thèse porte sur la conception d'amplificateurs de puissance reconfigurables en technologie CMOS avancée pour une application cellulaire de 4ème génération. Dans les systèmes de communication sans fil, le rendement énergétique est un critère primordial qui impacte la durée d'utilisation de la batterie. Principalement déterminé par la consommation d'énergie du transmetteur, il est plus particulièrement lié à celle de l'amplificateur de puissance (PA). Pour les terminaux mobiles de 4ème génération (4G), les techniques de transmission et les modulations utilisées pour atteindre les débits de données visés induisant une dynamique importante du signal à transmettre, l'implémentation de techniques d'amélioration du rendement autour du PA devient indispensable, afin de le reconfigurer en puissance.Nous avons mis au point dans ce travail de recherche des architectures innovantes utilisant les techniques d'amélioration du Power Cell Switching (PCS) et de l'Envelope Tracking (ET). Le double objectif visé étant d'améliorer significativement le rendement pour les faibles niveaux de puissance et d'apporter de la flexibilité par rapport à un PA utilisé seul. Une première architecture utilisant la technique du PCS totalement intégré en technologie CMOS 65nm de STMicroelectronics, mettant en œuvre des transformateurs comme combineurs de puissance, a été réalisée pour valider la fonctionnalité du concept proposé. Puis une deuxième architecture combinant les techniques du PCS et de l'ET a été conçue, afin d'évaluer les avantages qu'apporte la combinaison de ces deux techniques par rapport à un PA fonctionnant seul et à un PA développé utilisant la technique du PCS.

Download or read book Circuits for Electronic Instrumentation written by Thomas Henry O'Dell and published by Cambridge University Press. This book was released on 1991-08-30 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an up-to-date text on electronic circuit design. The subject is dealt with from an experimental point of view, but this has not restricted the author to well-known or simple circuits. Indeed, some very recent and quite advanced circuit ideas are put forward for experimental work. Each chapter takes up a particular type of circuit, and then leads the reader on to gain an understanding of how these circuits work by proposing experimental circuits for the reader to build and make measurements on. This is the first book to take such a practical approach to this level. The book will be useful to final year undergraduates and postgraduates in electronics, practising engineers, and workers in all fields where electronic instrumentation is used and there is a need to understand electronics and the interface between the instrument and the user's own experimental system. The book's references will also be a very helpful guide to the literature.

Available in PDF, EPUB and Kindle. Book excerpt: Concisely covers all the important concepts in an easy-to-understand way Gaining a strong sense of signals and systems fundamentals is key for general proficiency in any electronic engineering discipline, and critical for specialists in signal processing, communication, and control. At the same time, there is a pressing need to gain mastery of these concepts quickly, and in a manner that will be immediately applicable in the real word. Simultaneous study of both continuous and discrete signals and systems presents a much easy path to understanding signals and systems analysis. In A Practical Approach to Signals and Systems, Sundararajan details the discrete version first followed by the corresponding continuous version for each topic, as discrete signals and systems are more often used in practice and their concepts are relatively easier to understand. In addition to examples of typical applications of analysis methods, the author gives comprehensive coverage of transform methods, emphasizing practical methods of analysis and physical interpretations of concepts. Gives equal emphasis to theory and practice Presents methods that can be immediately applied Complete treatment of transform methods Expanded coverage of Fourier analysis Self-contained: starts from the basics and discusses applications Visual aids and examples makes the subject easier to understand End-of-chapter exercises, with a extensive solutions manual for instructors MATLAB software for readers to download and practice on their own Presentation slides with book figures and slides with lecture notes A Practical Approach to Signals and Systems is an excellent resource for the electrical engineering student or professional to quickly gain an understanding of signal analysis concepts - concepts which all electrical engineers will eventually encounter no matter what their specialization. For aspiring engineers in signal processing, communication, and control, the topics presented will form a sound foundation to their future study, while allowing them to quickly move on to more advanced topics in the area. Scientists in chemical, mechanical, and biomedical areas will also benefit from this book, as increasing overlap with electrical engineering solutions and applications will require a working understanding of signals. Compact and self contained, A Practical Approach to Signals and Systems be used for courses or self-study, or as a reference book.

Download or read book A Foundation in Digital Communication written by Amos Lapidoth and published by Cambridge University Press. This book was released on 2009-07-09 with total page 750 pages. Available in PDF, EPUB and Kindle. Book excerpt: This intuitive yet rigourous introduction derives the core results of digital communication from first principles. Theory, rather than industry standards, motivates the engineering approaches, and key results are stated with all the required assumptions. The book emphasizes the geometric view, opening with the inner product, the matched filter for its computation, Parseval's theorem, the sampling theorem as an orthonormal expansion, the isometry between passband signals and their baseband representation, and the spectral-efficiency optimality of quadrature amplitude modulation (QAM). Subsequent chapters address noise, hypothesis testing, Gaussian stochastic processes, and the sufficiency of the matched filter outputs. Uniquely, there is a treatment of white noise without generalized functions, and of the power spectral density without artificial random jitters and random phases in the analysis of QAM. This systematic and insightful book, with over 300 exercises, is ideal for graduate courses in digital communication, and for anyone asking 'why' and not just 'how'.
