Available in PDF, EPUB and Kindle. Book excerpt: Avec l'évolution des procédés technologiques d'intégration, le traitement numérique devient de plus en plus rapide tout en coûtant moins en surface et en consommation d'énergie. La diminution des dimensions est effectuée au détriment de la précision des blocs analogiques. L'idée est de bénéficier des performances offertes par les circuits numériques pour relâcher les spécifications des blocs analogiques et gagner ainsi globalement en surface et consommation. Or les concepteurs de circuits mixtes analogiques-numériques sont confrontés à une situation où ils doivent choisir entre un flot purement analogique et un flot purement numérique, chacun des deux ignorant l'autre. Cette thèse propose un flot de conception mixte du dessin des masques en unifiant le flot de conception numérique et analogique Dans une phase de placement, le concepteur est amené à décrire un placement relatif de son circuit sous la forme d'un script permettant à notre outil de générer un ensemble de placements valides. Par la suite, une phase de routage global détermine de manière grossière les chemins les plus courts permettant de joindre les connecteurs de chaque net. Ces chemins prennent en compte diverses contraintes du circuit telles que des obstacles ou des contraintes de symétrie. Une phase de routage détaillé vient ensuite compléter la construction et la résolution des problèmes de superposition des fils de routage. Notre flot de conception est appliqué à plusieurs circuits analogiques et mixtes de tailles différentes. Notre approche a pour objectif de donner du contrôle aux concepteurs tout au long de la conception du dessin des masques.

Download or read book Nano-scale CMOS Analog Circuits written by Soumya Pandit and published by CRC Press. This book was released on 2018-09-03 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reliability concerns and the limitations of process technology can sometimes restrict the innovation process involved in designing nano-scale analog circuits. The success of nano-scale analog circuit design requires repeat experimentation, correct analysis of the device physics, process technology, and adequate use of the knowledge database. Starting with the basics, Nano-Scale CMOS Analog Circuits: Models and CAD Techniques for High-Level Design introduces the essential fundamental concepts for designing analog circuits with optimal performances. This book explains the links between the physics and technology of scaled MOS transistors and the design and simulation of nano-scale analog circuits. It also explores the development of structured computer-aided design (CAD) techniques for architecture-level and circuit-level design of analog circuits. The book outlines the general trends of technology scaling with respect to device geometry, process parameters, and supply voltage. It describes models and optimization techniques, as well as the compact modeling of scaled MOS transistors for VLSI circuit simulation. • Includes two learning-based methods: the artificial neural network (ANN) and the least-squares support vector machine (LS-SVM) method • Provides case studies demonstrating the practical use of these two methods • Explores circuit sizing and specification translation tasks • Introduces the particle swarm optimization technique and provides examples of sizing analog circuits • Discusses the advanced effects of scaled MOS transistors like narrow width effects, and vertical and lateral channel engineering Nano-Scale CMOS Analog Circuits: Models and CAD Techniques for High-Level Design describes the models and CAD techniques, explores the physics of MOS transistors, and considers the design challenges involving statistical variations of process technology parameters and reliability constraints related to circuit design.

Book Synopsis Quantum Communications and Cryptography by : Alexander V. Sergienko
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.

Book Synopsis The gm/ID Methodology, a sizing tool for low-voltage analog CMOS Circuits by : Paul Jespers
Download or read book The gm/ID Methodology, a sizing tool for low-voltage analog CMOS Circuits written by Paul Jespers and published by Springer Science & Business Media. This book was released on 2009-12-01 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: IC designers appraise currently MOS transistor geometries and currents to compromise objectives like gain-bandwidth, slew-rate, dynamic range, noise, non-linear distortion, etc. Making optimal choices is a difficult task. How to minimize for instance the power consumption of an operational amplifier without too much penalty regarding area while keeping the gain-bandwidth unaffected in the same time? Moderate inversion yields high gains, but the concomitant area increase adds parasitics that restrict bandwidth. Which methodology to use in order to come across the best compromise(s)? Is synthesis a mixture of design experience combined with cut and tries or is it a constrained multivariate optimization problem, or a mixture? Optimization algorithms are attractive from a system perspective of course, but what about low-voltage low-power circuits, requiring a more physical approach? The connections amid transistor physics and circuits are intricate and their interactions not always easy to describe in terms of existing software packages. The gm/ID synthesis methodology is adapted to CMOS analog circuits for the transconductance over drain current ratio combines most of the ingredients needed in order to determine transistors sizes and DC currents.
