Electronic Devices For Analog Signal Processing

Electronic Devices for Analog Signal Processing is intended for engineers and post graduates and considers electronic devices applied to process analog signals in instrument making, automation, measurements, and other branches of technology. They perform various transformations of electrical signals: scaling, integration, logarithming, etc. The need in their deeper study is caused, on the one hand, by the extension of the forms of the input signal and increasing accuracy and performance of such devices, and on the other hand, new devices constantly emerge and are already widely used in practice, but no information about them are written in books on electronics. The basic approach of presenting the material in Electronic Devices for Analog Signal Processing can be formulated as follows: the study with help from self-education. While divided into seven chapters, each chapter contains theoretical material, examples of practical problems, questions and tests. The most difficult questions are marked by a diamond and can be given to advanced readers. Paragraphs marked by /// are very important for the understanding of the studied material and together they can serve a brief summary of a section. The text marked by italic indicates new or non-traditional concepts. Calculated examples are indicated by >. The main goal of Electronic Devices for Analog Signal Processing is not only to give some knowledge on modern electronic devices, but also to inspire readers on the more detailed study of these devices, understanding of their operation, ability to analyze circuits, synthesize new devices, and assess the possibilities of their application for solution of particular practical problems.

This book presents theory, design methods and novel applications for integrated circuits for analog signal processing. The discussion covers a wide variety of active devices, active elements and amplifiers, working in voltage mode, current mode and mixed mode. This includes voltage operational amplifiers, current operational amplifiers, operational transconductance amplifiers, operational transresistance amplifiers, current conveyors, current differencing transconductance amplifiers, etc. Design methods and challenges posed by nanometer technology are discussed and applications described, including signal amplification, filtering, data acquisition systems such as neural recording, sensor conditioning such as biomedical implants, actuator conditioning, noise generators, oscillators, mixers, etc. Presents analysis and synthesis methods to generate all circuit topologies from which the designer can select the best one for the desired application; Includes design guidelines for active devices/elements with low voltage and low power constraints; Offers guidelines for selecting the right active devices/elements in the design of linear and nonlinear circuits; Discusses optimization of the active devices/elements for process and manufacturing issues of nanometer technology.

Many digital control circuits in current literature are described using analog transmittance. This may not always be acceptable, especially if the sampling frequency and power transistor switching frequencies are close to the band of interest. Therefore, a digital circuit is considered as a digital controller rather than an analog circuit. This helps to avoid errors and instability in high frequency components. Digital Signal Processing in Power Electronics Control Circuits covers problems concerning the design and realization of digital control algorithms for power electronics circuits using digital signal processing (DSP) methods. This book bridges the gap between power electronics and DSP. The following realizations of digital control circuits are considered: digital signal processors, microprocessors, microcontrollers, programmable digital circuits. Discussed in this book is signal processing, starting from analog signal acquisition, through its conversion to digital form, methods of its filtration and separation, and ending with pulse control of output power transistors. The book is focused on two applications for the considered methods of digital signal processing: an active power filter and a digital class D power amplifier. The major benefit to readers is the acquisition of specific knowledge concerning discussions on the processing of signals from voltage or current sensors using a digital signal processor and to the signals controlling the output inverter transistors. Included are some Matlab examples for illustration of the considered problems.

Analog Electronics is an 11-chapter text that covers the significant advances in several aspects of analog electronics, with emphasis on how analog circuits work. The opening chapters consider the passive and active components of analog circuits. The succeeding chapters deal with the amplification of audio-frequency electrical signals and their transformation into sound waves, as well as the passive signal processing and transmission. The discussion then shifts to the active signal processing in frequency and time domain. Other chapters examine the mechanism of radio-frequency circuits, signal sources, and power supplies. The closing chapter tackles the commercial and professional application of electronics. This book will prove useful to engineers, technicians, and students.

Many instrumentation engineers and scientists often deal with analog electronic issues when approaching delicate measurements. Even if off-the-shelf measuring solutions exist, comprehension of the analog behavior of the measuring system is often a necessity. This book provides a concise introduction to the main elements of a low frequency analog acquisition chain. It aims to be sufficiently general to provide an introduction, yet specific enough to guide the reader through some classical problems that may be encountered in the subject. Topics include sensors, conditioning circuits, differential and instrumentation amplifiers, active filters (mainly for anti-aliasing purposes) and analog to digital converters. A chapter is devoted to an introduction to noise and electronic compatibility. This work is intended for people with a general background in electronics and signal processing, who are looking for an introduction to classical electronic solutions employed in measuring instruments involving low frequency analog signal processing.

Die Lösung der meisten Designprobleme bei analogen Schaltkreisen erfordert ein hohes Maß an Kreativität. Die Autoren dieses bahnbrechenden Leitfadens zeigen auf, daß die Lösung für fast alle analogen Signalverarbeitungsprobleme nicht notwendigerweise schwierig sein muß. In einem originellen, designorientierten Ansatz erfährt der Leser in fünf Schritten, wie er Problemstellungen mit Hilfe von integrierten Standardschaltkreisen als Bausatz löst. Anders als andere Autoren, behandeln Pallás-Areny und Webster Designprobleme zunächst aus funktionaler Sicht und entwickeln dann mögliche Lösungen auf der Basis vorhandener integrierter Schaltkreise, wobei der Schwerpunkt auf der Schaltkreisleistung liegt und nicht auf der inneren Struktur. In fünf Schritten geht es von der Signalklassifiktaion, der Definition gewünschter Funktionen über die Beschreibung analoger Hauptumsetzer hin zu Fehlerklassifikation und -analyse. Mit 90 praktischen Beispielen und über 130 Übungsaufgaben. Ein hilfreiches Nachschlagewerk für die Praxis und ein Lehrbuch für fortgeschrittene Studenten. (02/99)
