In general about the book

Analog integrated circuits (AICs) deal with the design and analysis of modern circuits using integrated bipolar junction transistor, junction field-effect transistor and metal-oxide- semiconductor field-effect transistor technologies. The field of study we call analog electronics encompasses a broad range of specialty areas including audio systems, communications systems, instrumentation, electromedical systems, automatic controls, e tc. Integrated operational amplifiers (OPAMPs) are the most universal building blocks of contemporary AICs. Since their properties are very nearly ideal, the basic approach to a design problem consists of finding the feedback network best suited to the given problem. The possibilities of building an external feedback circuitry around the OPAMP are practically unlimited.

This text is devoted to the use of OPAMP devices in analog and linear circuits that are used extensively for amplification and signal processing. In the preparation of the text the author has assumed that the reader is familiar with the basic theory and principles of solid-state devices. Therefore, the solid-state device theory, which is already covered elsewhere in the literature, is omitted, and all of the space is devoted to circuit approach unique to operation of OPAMPs.

The book is divided into eleven chapters, General References, Glossary, Answer to Selected Odd-Numbered Problems, and Index.

Chapter content

To help the reader understand the basic OPAMP principles and analysis techniques Chapter 1 starts with some general models of linear amplifier circuits, definitions, and parameters.

Chapter 2 introduces fundamental concepts and applications based on OPAMP as predominantly ideal devices.

Practical limitations of realistic OPAMPs are the subject of Chapter 3 and 4. Chapter 3 addresses dc effects, including the effect of finite gain, finite input impedance, non-zero output impedance, input offset voltage, and input bias currents. Chapter 4 addresses dynamic limitations in both the frequency and time domains. Primary topics include closed-loop bandwidth relationships, effects of slew-rate, and common-mode rejection.

General OPAMP applications such as integrators, differentiators, phase-shift networks, instrumentation amplifiers, and operation with single power supply are covered in Chapter 5.

Chapter 6 studies comparators. The comparator is together with the OPAMP the basic block used in analog signal processors. Ideally, it generates an output logic signal as response to an analog input. Both open-loop comparators and comparators with feedback (Schmidt trigger) are considered.

Chapter 7 covers signal generators, including astable multivibrator, 555 timer, square/triangle waveforms function generator, Wien-bridge and phase-shift oscillators, and the 8038 function generator chip.

Chapter 8 deals with active filter design. The main topics considered here are related to Butterworth filter responses, low-pass and high-pass unity-gain designs, low-pass and high-pass equal-component designs, multiple-feedback band-pass filter, and state variable filter.

Chapter 9 concentrates on regulation. Signal-processing rectifier circuits, holding circuits, limiting circuits, voltage references and linear voltage regulators have been combined into a single chapter.

Chapter 10 deals with data conversion. Both digital-to-analog and analog-to-digital circuits, that represent the bridge between the analog and digital worlds, are systematically treated. In addition analog switches and multiplexers, and voltage-to-frequency converters are considered. Chapter 11 concludes the book with a variety of nonlinear circuits, such as multipliers and logarithmic amplifiers. The material has been expanded with the inclusion of phase-locked loops.

The book contains numerous examples, many of which include commercial analog circuits. End of chapter problems are given, many of them illustrating practical circuits.

Useful book

Linear integrated circuits such as OPAMPs, converters, comparators, and function generators have become a fundamental part of today's electronic systems. Bearing this in mind, the principles of operation, electrical specifications, and ac and dc limitations of linear integrated circuits are essential. In my opinion this book is the right blend of theory and practice, and presents analog integrated circuit's theory in a practical way, which is most needed in industry today. This book may be used in a variety of modes, ranging from a text for one-semester course for senior level or first-year graduate students in electrical engineering, as well as reference work for practicing engineers who need more detailed information on various aspects of analog circuits. I encourage everyone who uses or teaches operational amplifiers with linear integrated circuits to get a copy of the book. It is definitely recommended for practicing engineers and educators alike.
