This book presents innovative solutions in the design of precision instrumentation amplifier and read-out ICs, which can be used to boost millivolt-level signals transmitted by modern sensors, to levels compatible with the input ranges of typical Analog-to-Digital Converters (ADCs). The discussion includes the theory, design and realization of interface electronics for bridge transducers and thermocouples. It describes the use of power efficient techniques to mitigate low frequency errors, resulting in interface electronics with high accuracy, low noise and low drift. Since this book is mainly about techniques for eliminating low frequency errors, it describes the nature of these errors and the associated dynamic offset cancellation techniques used to mitigate them.

This book describes a new way to design and utilize Instrumentation Amplifiers (IAs) by taking advantages of the current-mode (CM) approach. For the first time, all different topologies of CMIAs are discussed and compared, providing a single-source reference for instrumentation and measurement experts who want to choose a topology for a specific application. The authors also explain major challenges in designing CMIAs, so the book can be useful for anyone studying instrumentation amplifiers, and even other analog circuits. Coverage also includes various CM signal processing techniques employed in CMIAs, and applications of the CMIAs in biomedical and data acquisition are demonstrated.

An analog chip is a set of miniature electronic analog circuits formed on a single piece of semiconductor material. The voltage and current at specified points in the circuits of analog chips vary continuously in time. In contrast, digital chips only use and create voltages or currents at discrete levels, with no intermediate values. In addition to Transistors, analog chips often have a larger number of passive elements than digital chips typically do. Inductors tend to be avoided because of their large size and a transistor and capacitor together can do the work of an inductor. The book broadly deals with: Direct and capacitor coupled Opamp amplifiers; Frequency response and compensation to improve the performance of Opamp circuits; Voltage and current sources, instrumentation amplifiers and precision rectifiers, limiting and clamping circuits; Log and antilog amplifiers, etc. The book covers the syllabus prescribed for B.E. Care is taken to develop the subject logically so that the book could also be used by B.Sc. and diploma students. Neatly drawn diagrams, stepwise illustrations, and graded numerical examples, are included in every chapter to support the contents.

Operational Amplifiers – Theory and Design, Second Edition presents a systematic circuit design of operational amplifiers. Containing state-of-the-art material as well as the essentials, the book is written to appeal to both the circuit designer and the system designer. It is shown that the topology of all operational amplifiers can be divided into nine main overall configurations. These configurations range from one gain stage up to four or more stages. Many famous designs are evaluated in depth. Additional chapters included are on systematic design of μV-offset operational amplifiers and precision instrumentation amplifiers by applying chopping, auto-zeroing, and dynamic element-matching techniques. Also, techniques for frequency compensation of amplifiers with high capacitive loads have been added. Operational Amplifiers – Theory and Design, Second Edition presents high-frequency compensation techniques to HF-stabilize all nine configurations. Special emphasis is placed on low-power low-voltage architectures with rail-to-rail input and output ranges. In addition to presenting characterization of operational amplifiers by macro models and error matrices, together with measurement techniques for their parameters it also develops the design of fully differential operational amplifiers and operational floating amplifiers. Operational Amplifiers – Theory and Design, Second Edition is carefully structured and enriched by numerous figures, problems and simulation exercises and is ideal for the purpose of self-study and self-evaluation.

Linear IC's as Sensor Signal Conditioning Amplifiers is an advanced application-based engineering technology textbook introducing operational amplifiers as sensor scaling circuits. The text employs a unique single circuit approach to develop signal conditioning amplifier design from the common single-ended inverting amplifier through multi-stage differential instrumentation-grade amplifiers. Text chapters address linear sensors, measurement systems; op amp circuit design; gain, offset and calibration considerations; and specification interpretation of strain gauges, load cells, accelerometers, thermocouples, pressure and other low-level sensors commonly employed in product testing applications. The text is nine chapters, 535 pages, includes fifteen operational amplifier lab experiments and is suggested for sophomore or junior-year engineering technology students and practitioners of sensor-based data acquisition as commonly applied in experimental testing, research and product development.

"In this fifth edition, we not only have kept the standard 741 op amp but also have shown many circuits with newer, readily available op amps because these have largely overcome the dc and ac limitations of the older types. We preserved or objective of simplifying the process of learning about applications involving signal conditioning, signal generation, filters, instrumentation, and control circuits. But we have oriented this fifth edition to reflect the evolution of analog circuits into those applications whose purpose is to condition signals from transducers or other sources into form suitable for presentation to a microcontroller or computer. In addition, we have added examples of circuit simulation using PSpice throughout this edition."--Introduction.
