ELECTRONIC DEVICES AND CIRCUIT THEORY

It is now some 50 years since the first transistor was introduced on December 23, 1947. For those of us who experienced the change from glass envelope tubes to the solid-state era, it still seems like a few short years ago. The first edition of this text contained heavy coverage of tubes, with succeeding editions involving the important decision of how much coverage should be dedicated to tubes and how much to semiconductor devices. It no longer seems valid to mention tubes at all or to compare the advantages of one over the other—we are firmly in the solid-state era. The miniaturization that has resulted leaves us to wonder about its limits. Complete systems now appear on wafers thousands of times smaller than the single element of earlier networks. New designs and systems surface weekly. The engineer becomes more and more limited in his or her knowledge of the broad range of advances— it is difficult enough simply to stay abreast of the changes in one area of research or development. We have also reached a point at which the primary purpose of the container is simply to provide some means of handling the device or system and to provide a mechanism for attachment to the remainder of the network. Miniaturization appears to be limited by three factors (each of which will be addressed in this text): the quality of the semiconductor material itself, the network design technique, and the limits of the manufacturing and processing equipment

Electronic Circuit Analysis

Since publishing first edition of this book three years back, there are few additions in the subject and also as a result of receiving some feedback, it has become imperative to bring another edition to cover the lapses and bring the text mor:e useful to students. In the second edition, I have reorganised the chapters and also added few subchapters like High Frequency Amplifiers, Stability Considerations, UPS and SMPS in the respective chapters. The author is indebted to Sri. M.V. Ramanaiah, Associate Professor in the Department of ECE, Gokaraju Rangaraju Institute of Engineering and Technology, Hyderabad for his efforts in going through the book and making the symbols etc. more perfect which were cropped up at the time of typing the text.

Мустақиллик йилларида олдинги тизимдан мерос бўлиб қолган, маънавий ва жисмоний эскирган асосий воситаларни юксак даражадаги замонавий техника ва юқори технологияларга алмаштириш, уларни ишлаб чиқаришга татбиқ этиш орқали инновацион иқтисодиётга ўтиш борасида катта саъй-ҳаракатлар қилинмоқда. "2017-2021 йилларда Ўзбекистон Республикасини ривожлантиришнинг бешта устувор йўналиши бўйича Ҳаракатлар стратегияси"нинг қабул қилиниши, 2018 йилнинг юртимизда “Фаол тадбиркорлик, инновацион ғоялар 2 ва технологияларни қўллаб қувватлаш йили" деб эълон қилиниши ҳам мазкур йўналишда қўйилган муҳим қадамдир. Зеро, "Инновация бу келажак дегани.

Electronic and Optoelectronic Properties of Semiconductor Structures

Semiconductor-based technologies continue to evolve and astound us. New materials, new structures, and new manufacturing tools have allowed novel high performance electronic and optoelectronic devices. To understand modern semiconductor devices and to design future devices, it is important that one know the underlying physical phenomena that are exploited for devices. This includes the properties of electrons in semiconductors and their heterostructures and how these electrons respond to the outside world. This book is written for a reader who is interested in not only the physics of semiconductors, but also in how this physics can be exploited for devices. The text addresses the following areas of semiconductor physics: i) electronic properties of semiconductors including bandstructures, effective mass concept, donors, acceptors, excitons, etc.; ii) techniques that allow modifications of electronic properties; use of alloys, quantum wells, strain and polar charge are discussed; iii) electron (hole) transport and optical properties of semiconductors and their heterostructures; and iv) behavior of electrons in small and disordered structures. As much as possible I have attempted to relate semiconductor physics to modern device developments.

ELECTROMAGNETICS

This book is intended as a text for a first-year graduate sequence in engineering electromagnetics. Ideally such a sequence provides a transition period during which a student can solidify his or her understanding of fundamental concepts before proceeding to specialized areas of research. The assumed background of the reader is limited to standard undergraduate topics in physics and mathematics. Worthy of explicit mention are complex arithmetic, vector analysis, ordinary differential equations, and certain topics normally covered in a “signals and systems” course (e.g., convolution and the Fourier transform). Further analytical tools, such as contour integration, dyadic analysis, and separation of variables, are covered in a self-contained mathematical appendix.
