Designed for graduate and upper-level undergraduate engineering students, this is an introduction to control systems, their functions, and their current role in engineering design. Organized from a design rather than an analysis viewpoint, it shows students how to carry out practical engineering design on all types of control systems. Covers basic analysis, operating and design techniques as well as hardware/software implementation. Includes case studies.
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.

This 2nd edition provides an in-depth, up-to-date, unified, and comprehensive treatment of the fundamentals of the theory of active networks and its applications to feedback amplifier design. The main purpose is to discuss the topics that are of fundamental importance that transcends the advent of new devices and design tools. Intended primarily as a text in circuit theory in electrical engineering for senior and/or first year graduate students, the book also serve as a reference for researchers and practicing engineers in industry.A special feature of the book is that it bridges the gap between theory and practice, with abundant examples showing how theory solves problems. These examples are actual practical problems, not idealized illustrations of the theory. The topic on topological analysis of active networks is also expanded to benefit more discerning readers.
This book, first published in 2004, is an expanded and thoroughly revised edition of Tom Lee's acclaimed guide to the design of gigahertz RF integrated circuits. A new chapter on the principles of wireless systems provides a bridge between system and circuit issues. The chapters on low-noise amplifiers, oscillators and phase noise have been significantly expanded. The chapter on architectures now contains several examples of complete chip designs, including a GPS receiver and a wireless LAN transceiver, that bring together the theoretical and practical elements involved in producing a prototype chip. Every section has been revised and updated with findings in the field and the book is packed with physical insights and design tips, and includes a historical overview that sets the whole field in context. With hundreds of circuit diagrams and homework problems this is an ideal textbook for students taking courses on RF design and a valuable reference for practising engineers.
Active Network Analysis gives a comprehensive treatment of the fundamentals of the theory of active networks and its applications to feedback amplifiers. The guiding light throughout has been to extract the essence of the theory and to discuss those topics that are of fundamental importance and that will transcend the advent of new devices and design tools. The book provides under one cover a unified, comprehensive, and up-to-date coverage of these recent developments and their practical engineering applications. In selecting the level of presentation, considerable attention has been given to the fact that many readers may be encountering some of these topics for the first time. Thus basic introductory material has been included. The work is illustrated by a large number of carefully chosen and well-prepared examples.
