An investigation was performed to determine which of two basic feedback-amplifier design procedures, the Bode method or the root-locus technique, would result in the better amplifier in terms of the amplifier's gain, bandwidth and desensitivity. Five amplifiers were considered, two using the Bode procedure and three using the root-locus techniques. Each represented a prominent variation within the Bode or root-locus method. The modifications were performed to give a ''best-versus-best'' comparison of the design methods. To obtain an equitable comparison the same requirements of over-all gain and bandwidth were applied in each design, and the same transistors and transistor model were used for all calculations. In each case the amplifier was designed and constructed, and its performance was evaluated. The results of the experimental work show that the best amplifiers designed using the root-locus technique give a better performance than the best amplifier designed by the Bode method. Qualitatively as well as quantitatively, the root locus produced the better amplifier because of the versatility of the design procedure with respect to the various types of requirements it can accommodate.

The operational amplifier ("op amp") is the most versatile and widely used type of analog IC, used in audio and voltage amplifiers, signal conditioners, signal converters, oscillators, and analog computing systems. Almost every electronic device uses at least one op amp. This book is Texas Instruments' complete professional-level tutorial and reference to operational amplifier theory and applications. Among the topics covered are basic op amp physics (including reviews of current and voltage division, Thevenin's theorem, and transistor models), idealized op amp operation and configuration, feedback theory and methods, single and dual supply operation, understanding op amp parameters, minimizing noise in op amp circuits, and practical applications such as instrumentation amplifiers, signal conditioning, oscillators, active filters, load and level conversions, and analog computing. There is also extensive coverage of circuit construction techniques, including circuit board design, grounding, input and output isolation, using decoupling capacitors, and frequency characteristics of passive components. The material in this book is applicable to all op amp ICs from all manufacturers, not just TI. Unlike textbook treatments of op amp theory that tend to focus on idealized op amp models and configuration, this title uses idealized models only when necessary to explain op amp theory. The bulk of this book is on real-world op amps and their applications; considerations such as thermal effects, circuit noise, circuit buffering, selection of appropriate op amps for a given application, and unexpected effects in passive components are all discussed in detail. *Published in conjunction with Texas Instruments *A single volume, professional-level guide to op amp theory and applications *Covers circuit board layout techniques for manufacturing op amp circuits.

The only method of circuit analysis known to most engineers and students is nodal or loop analysis. Although this works well for obtaining numerical solutions, it is almost useless for obtaining analytical solutions in all but the simplest cases. In this unusual 2002 book, Vorpérian describes remarkable alternative techniques to solve, almost by inspection, complicated linear circuits in symbolic form and obtain meaningful analytical answers for any transfer function or impedance. Although not intended to replace traditional computer-based methods, these techniques provide engineers with a powerful set of tools for tackling circuit design problems. They also have great value in enhancing students' understanding of circuit operation, making this an ideal course book, and numerous problems and worked examples are included. Originally developed by Professor David Middlebrook and others at Caltech (California Institute of Technology), the techniques described here are now widely taught at institutions and companies around the world.

Culled from the pages of CRC's highly successful, best-selling The Circuits and Filters Handbook, Second Edition, Circuit Analysis and Feedback Amplifier Theory presents a sharply focused, comprehensive review of the fundamental theory behind professional applications of circuits and feedback amplifiers. It supplies a concise, convenient reference to the key concepts, models, and equations necessary to analyze, design, and predict the behavior of large-scale circuits and feedback amplifiers, illustrated by frequent examples. Edited by a distinguished authority, this book emphasizes the theoretical concepts underlying the processes, behavior, and operation of these devices. It includes guidance on the design of multiple-loop feedback amplifiers. More than 350 figures and tables illustrate the concepts, and where necessary, the theories, principles, and mathematics of some subjects are reviewed. Expert contributors discuss analysis in the time and frequency domains, symbolic analysis, state-variable techniques, feedback amplifier configurations, general feedback theory, and network functions and feedback, among many other topics. Circuit Analysis and Feedback Amplifier Theory builds a strong theoretical foundation for the design and analysis of advanced circuits and feedback amplifiers while serving as a handy reference for experienced engineers, making it a must-have for both beginners and seasoned experts.
