This research examines a unified approach to several of the problems associated with Operational Amplifiers (OAs), namely, speed, accuracy, and frequency dependent gain. The approach which is examined is the Composite Operational Amplifier(CNOA), where N=2, 3, or 4 single OAs. The CNOA is found to greatly extend the useful operating frequencies of the OA while maintaining low sensitivity to circuit element variations and a high degree of stability. It also provides a method for obtaining a fast and accurate OA. An additional feature of the CNOA is that can be implemented using current technology. A computer model for the single OA was created and validated, and provided the basis for proving the superiority of the CNOA. Theoretical and experimental results were used with these computer simulation results to fully substantiate the findings. (Theses) (Author).

Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thougtit that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 31 (thesis year 1986) a total of 11 ,480 theses titles trom 24 Canadian and 182 United States universities. We are sure that this broader base tor these titles reported will greatly enhance the value ot this important annual reterence work. While Volume 31 reports theses submitted in 1986, on occasion, certain univer sities do re port theses submitted in previousyears but not reported at the time.

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.

A general approach for extending the useful operating frequencies of linear active networks is the Composite Operational Amplifier. The Composite Operational Amplifier is generated by replacing single operational amplifiers with a network of N operational amplifiers (CNOA). This novel approach is extended to the integrated circuit. Three, 2 operational amplifier (C20A), composite forms are integrated on to a single chip. Additionally, the resistor network of the composite is constructed to be digitally programmable making the composite operational amplifiers capable of different Q factors. The chip is constructed with 200 transistors, four capacitors, and 10 resistors as major components. The overall size of the chip is 136 by 1285 mils and is packaged in a 24 pin dual in-line package (DIP). (Thesis).

The goal of this book is to encourage the reader to become proficient in the analysis and design of circuits utilizing modern linear integrated circuits. It progresses from the fundamental circuit building blocks through to analog and digital conversion systems. A methodical step-by-step presentation introduces the basic idealized operational amplifiers and eventually examines practical limitations in great detail. Each chapter has a problem set and contains extended topic to present extra discussion and details about the subject.
