This book was released on 2005 with total page 171 pages. Available in PDF, EPUB and Kindle. Book excerpt: Le travail présenté dans cette thèse contribue au développement d'opérateurs analogiques faible tension et faible consommation en CMOS pour le traitement du signal sur puce. Il s'inscrit dans le cadre du développement de systèmes miniaturisés de microanalyse pour applications biomédicales. Un opérateur étudié est un OTA (Amplificateur Opérationnel de Transconductance) de faible transconductance Gm. C'est un bloc clé pour concevoir des filtres Gm-C monolithique très basses fréquences. On peut montrer que l'OTA à base de transistors MOS à entrées multiples et grilles flottantes (MIFG-MOS) fonctionnant en faible inversion permet à la fois l'obtention de faible Gm et l'extension de la zone linéaire. La linéarité peut encore être améliorée jusqu'aux limites de la tension d'alimentation par l'implémentation d'une technique de suppression du terme de distorsion cubique. On propose ainsi des structures d'OTA sous 1,5V avec une consommation inférieure à 1μW pour des filtres Gm-C à très faibles fréquences de coupures. D'autres opérateurs, comme par exemple le multiplieur, sont aussi étudiés. Là encore, en utilisant des transistors MIFG-MOS et en appliquant la technique d'annulation du terme de distorsion cubique, plusieurs structures d'opérateurs faibles tensions mais avec une grande plage dynamique sont développées

Book Synopsis Continuous-Time Sigma-Delta A/D Conversion by : Friedel Gerfers
Download or read book Continuous-Time Sigma-Delta A/D Conversion written by Friedel Gerfers and published by Springer Science & Business Media. This book was released on 2006-02-27 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sigma-delta A/D converters are a key building block in wireless and multimedia applications. This comprehensive book deals with all relevant aspects arising during the analysis, design and simulation of the now widespread continuous-time implementations of sigma-delta modulators. The results of several years of research by the authors in the field of CT sigma-delta modulators are covered, including the analysis and modeling of different CT modulator architectures, CT/DT loop filter synthesis, a detailed error analysis of all components, and possible compensation/correction schemes for the non-ideal behavior in CT sigma-delta modulators. Guidance for obtaining low-power consumption and several practical implementations are also presented. It is shown that all the proposed new theories, architectures and possible correction techniques have been confirmed by measurements on discrete or integrated circuits. Quantitative results are also provided, thus enabling prediction of the resulting accuracy.

Book Synopsis MOSFET Modeling & BSIM3 User’s Guide by : Yuhua Cheng
Download or read book MOSFET Modeling & BSIM3 User’s Guide written by Yuhua Cheng and published by Springer Science & Business Media. This book was released on 2007-05-08 with total page 467 pages. Available in PDF, EPUB and Kindle. Book excerpt: Circuit simulation is essential in integrated circuit design, and the accuracy of circuit simulation depends on the accuracy of the transistor model. BSIM3v3 (BSIM for Berkeley Short-channel IGFET Model) has been selected as the first MOSFET model for standardization by the Compact Model Council, a consortium of leading companies in semiconductor and design tools. In the next few years, many fabless and integrated semiconductor companies are expected to switch from dozens of other MOSFET models to BSIM3. This will require many device engineers and most circuit designers to learn the basics of BSIM3. MOSFET Modeling & BSIM3 User's Guide explains the detailed physical effects that are important in modeling MOSFETs, and presents the derivations of compact model expressions so that users can understand the physical meaning of the model equations and parameters. It is the first book devoted to BSIM3. It treats the BSIM3 model in detail as used in digital, analog and RF circuit design. It covers the complete set of models, i.e., I-V model, capacitance model, noise model, parasitics model, substrate current model, temperature effect model and non quasi-static model. MOSFET Modeling & BSIM3 User's Guide not only addresses the device modeling issues but also provides a user's guide to the device or circuit design engineers who use the BSIM3 model in digital/analog circuit design, RF modeling, statistical modeling, and technology prediction. This book is written for circuit designers and device engineers, as well as device scientists worldwide. It is also suitable as a reference for graduate courses and courses in circuit design or device modelling. Furthermore, it can be used as a textbook for industry courses devoted to BSIM3. MOSFET Modeling & BSIM3 User's Guide is comprehensive and practical. It is balanced between the background information and advanced discussion of BSIM3. It is helpful to experts and students alike.

Book Synopsis Masters Theses in the Pure and Applied Sciences by : Wade H. Shafer
Download or read book Masters Theses in the Pure and Applied Sciences written by Wade H. Shafer and published by Springer. This book was released on 1976 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and dis· seminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) *at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the ac· tivity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volume were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 20 (thesis year 1975) a total of 10,374 theses titles from 28 Canadian and 239 United States universities. We are sure that this broader base for theses titles reported will greatly enhance the value of this important annual reference work. The organization of Volume 20 is identical to that of past years. It consists of theses titles arranged by discipline and by university within each discipline.

Download or read book Bolometers written by Torrence M. Walcott and published by . This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A bolometer is a device for measuring the energy of incident electromagnetic radiation. It consists of an "absorber" connected to a heat sink through an insulating link. The result is that any radiation absorbed by the absorber raises its temperature above that of the heat sink; then the higher the energy absorbed, the higher the temperature will be. This book gathers and presents current research in the study of bolometers including investigations of properties of high temperature superconducting bolometers, operating uncooled resistive bolometers in a closed-loop mode, as well as a review on thin-film micro-bolometers with Si-Ge thermo-sensing films deposited from plasma discharge.
