Electronics Basic Analog and Digital PDF

This book differs significantly from other current introductory textbooks on electronics in its coverage and approach. Most of the current textbooks pay only scant attention to basic electronics and the underlying theory of semiconductors. This, I believe, is a serious shortcoming, because some knowledge of the fundamental physical concepts involved is needed for two main reasons: first, in order to gain more than a superficial understanding of the behavior of semiconductor devices, and, second, to appreciate the nature of continuing improvements to the performance of these devices and therefore be able to follow the ongoing and projected advances in microelectronics. Given that the theory of electric conduction in semiconductors is well above the level of an introductory textbook, the challenge is to present the essentials of this theory in a way that gives at least a good qualitative understanding of the fundamental concepts involved. Fundamentals and concepts are strongly emphasized throughout this book, as in the author’s book Electric Circuits and Signals, CRC press, Boca Raton, Florida, 2008. The following are specific features of the book’s pedagogy:

1. Diffusion and drift in semiconductors and contacts between dissimilar materials are discussed in terms of electrochemical potential, which is shown to be a relatively simple but fundamental and unifying generalization of electric potential in the presence of concentration gradients. Most textbooks on electronics ignore electrochemical potential, and, if they go this far, consider instead Fermi and quasi-Fermi levels whose nature and role in semiconductors are not clearly addressed. Consequently, students find it difficult to understand why the Fermi level should be the same throughout a system at equilibrium, or the meaning of statements such as ‘‘Current is maintained by a gradient of the quasi-Fermi level,’’ or ‘‘A voltmeter actually measures the difference between quasi-Fermi levels.’’ An added benefit of introducing the concept of electrochemical potential is that electrophysiology of membranes of living cells is almost invariably discussed in terms of electrochemical potential. The concept of electrochemical potential provides an instructive link between semiconductor and ionic systems at a time when electrical engineering students are being increasingly exposed to biological systems.

2. An important objective in presenting semiconductor basics and operation of semiconductor devices is to ‘‘demystify’’ concepts and relations that are usually stated as facts, without at least some ‘‘plausible’’ explanation as to ‘‘the reason why.’’ It is shown how many of the basic relations can be quite simply derived from fundamental considerations. Where this represents a significant departure from the mainstream of the discussion, it is left to Special Examples and Topics on the website of the book at: www.crcpress.com=product=isbn=9781420087079

3. The discussion of transistors starts with the MOSFET; then the JFET and its derivative, the MESFET; and lastly the BJT. The discussion of BJT and MOSFET circuits is integrated as much as possible so as to highlight the common underlying principles, particularly as concerns negative feedback. GaAs is briefly considered and its main characteristics, advantages, and limitations are highlighted.

4. State-of-the-art technologies, such as silicon-on-insulator and SiGe technologies, are presented.

5. The discussion of power electronics includes a brief treatment of power switching and npnp devices.

6. The Introduction presents a brief history of electronics and its impact.

7. Practical, real-life material is included wherever appropriate, mainly in the form of ‘‘Application Windows’’ that apply theory and provide additional motivation for students.

8. PSpice1 simulations based on schematic capture and using OrCAD1 16.0 Demo Software are presented in some detail, including the simulation procedure, and are integrated within the discussion (OrCAD, PSpice, SPECTRA for OrCAD, and Cadence are registered trademarks of Cadence Design Systems, Inc., San Jose, California). The PSpice simulation examples are included on the website of the book. A free download of OrCAD Demo Software is announced at the Cadence website: https:==www.cadence.com=products/orcad=pages=downloads.aspx.
