Book Preface

This volume is intended together an electronic circuit style textbook and reference book; it begins at a level an ideal for those v no ahead exposure come electronics and also carries the reader v to a reasonable level of ability in electronic circuit design. We have used a straightforward technique to the essential concepts of circuit design, coupled v an in-depth choice of topics. We have attempted to integrate the pragmatic technique of the practicing physicist with the quantitative strategy of the engineer, who wants a thoroughly evaluated circuit design.

This book evolved native a collection of notes composed to accompany a one-semester food in laboratory electronic devices at Harvard. That course has a differed enrollment – undergraduates choose up an abilities for their eventual work in scientific research or industry, graduate students through a ar of research clearly in mind, and progressed graduate students and postdoctoral researchers who suddenly discover themselves hampered by their inability come “do electronics.”

It soon became clear the existing textbooks were poor for such a course. Although over there are wonderful treatments of each electronic devices specialty, composed for the planned sequence of a four-year design curriculum or for the practicing engineer, those books that effort to deal with the totality field of electronic devices seem to experience from excessive detail (the handbook syndrome), native oversimplification (the cookbook syndrome), or from bad balance of material. Lot of the favourite pedagogy of start textbooks is rather unnecessary and, in fact, is not offered by practicing engineers, while beneficial circuitry and methods of analysis in everyday use by circuit designers lie hidden in applications notes, design journals, and hard-to-get data books. In other words, over there is a tendency among textbook authors to stand for the theory, rather than the art, of electronics.

We collaborated in creating this publication with the certain intention of combining the discipline of a circuit design engineer v the perspective of a practicing speculative physicist and also teacher that electronics. Thus, the therapy in this publication reflects our viewpoint that electronics, as currently practiced, is usually a straightforward art, a mix of some straightforward laws, rules of thumb, and also a large bag that tricks. For these reasons we have omitted completely the normal discussions of solid-state physics, the h-parameter model of transistors, and facility network theory, and also reduced to a ceiling minimum the mention of fill lines and the s-plane. The therapy is mostly nonmathematical, with strong encouragement that circuit brainstorming and also mental (or, at most, back-of-the-envelope) calculate of circuit values and also performance.

In enhancement to the subjects usually treated in electronics books, us have consisted of the following:• one easy-to-use transistor model;• extensive discussion of advantageous subcircuits, such as present sources and also current mirrors;• single-supply op-amp design;• easy-to-understand discussions of subject on i m sorry practical design information is often challenging to find: opamp frequency compensation, low-noise circuits, phaselocked loops, and also precision direct design;• simplified architecture of active filters, with tables and also graphs;• a section on noise, shielding, and also grounding;• a distinct graphical an approach for streamlined low-noise amplifier analysis;• a chapter on voltage references and regulators, including consistent current supplies;• a conversation of monostable multivibrators and their idiosyncrasies;• a collection of digital logic pathology, and what come do about it;• comprehensive discussion the interfacing to logic, with emphasis on the brand-new NMOS and PMOS LSI;• a in-depth discussion that A/D and also D/A switch techniques;• a ar on digital noise generation;• a conversation of minicomputers and also interfacing to data buses, through an development to assembly language;• a chapter on microprocessors, with actual style examples and also discussion – exactly how to design them into instruments, and also how to do them perform what friend want;• a thing on building and construction techniques: prototyping, printed circuit boards, instrument design • a simplified way to evaluate high-speed switching circuits;• a thing on clinical measurement and data processing: what you deserve to measure and how accurately, and what to perform with the data;• bandwidth narrowing approaches made clear: signal averaging, multichannel scaling, lock-in amplifiers, and also pulseheight analysis;• amusing collections of “bad circuits,” and also collections that “circuit ideas”;• beneficial appendixes on exactly how to draw schematic diagrams,IC generic types, LC filter design, resistor values, oscilloscopes, math review, and others;• tables that diodes, transistors, FETs, op-amps, comparators, regulators, voltage references, microprocessors, and also other devices, generally listing the features of both the most popular and the best types.

Throughout us have adopted a approach of specify name names, frequently comparing the characteristics of competing devices for usage in any kind of circuit, and the benefits of alternate circuit configurations. Instance circuits are attracted with real device types, no black boxes. The overall intent is to bring the leader to the suggest of understanding plainly the selections one makes in developing a circuit – how to pick circuit configurations, an equipment types, and parts values. The usage of largely nonmathematical circuit architecture techniques go not result in circuits that cut corners or weaken performance or reliability. Top top the contrary, such techniques boost one’s understanding of the real choices and compromises challenged in design a circuit and also represent the best technique to good circuit design.

This publication can be used for a full-year digital circuit style course at the college level, with only a minimum mathematics prerequisite; namely, part acquaintance v trigonometric and also exponential functions, and preferably a bit of differential calculus. (A short review of complicated numbers and derivatives is included as an appendix.)

If the less essential sections space omitted, it deserve to serve as the message for a one-semester food (as it does in ~ Harvard). A separately accessible laboratory manual, Laboratory manual for the arts of electronic devices (Horowitz and Robinson, 1981), includes twenty-three laboratory exercises, together with reading and problem assignments keyed come the text. To assist the reader in navigation, we have actually designated with open boxes in the margin those sections within each chapter that we feel have the right to be safe passed over in an abbreviation reading. Because that a one-semester course it would more than likely be wise to omit, in addition, the products of chapter 5 (first half), 7, 12, 13, 14, and also possibly 15, as defined in the introductory paragraphs of those chapters.
