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.
In a world where great efforts are spent designing and creating more complex, yet efficient systems, sensing elements and related readout circuits, which constitute an integral part of them, need to be designed fulfilling these constraints, beside the common key parameters, such as high sensitivity, resolution and accuracy. Capacitive sensors and their differential subset provide virtually no energy dissipation, show insensitivity to temperature variations and have the capability to be micromachined directly onto a silicon substrate, together with the readout interface. Designing a readout circuit that takes advantage of these benefits, according to any specific application, is thus of utmost importance. This volume introduces the reader to state-of-the-art techniques and research achievements in interfacing differential capacitance sensors. Technical topics discussed in the book include:▪ Switched capacitor based interfaces;▪ Voltage mode, differential capacitance to time, voltage, digital converters;▪ Current mode interfaces based on standard components;▪ Current mode interfaces based on CCIIs and VCIIs;▪ Principles of second generation current and voltage conveyors. This book gives the reader a comprehensive overview on the working principles, equivalent circuit models and most advanced interfacing techniques for differential capacitive transducers, highlighting benefits and downsides of each option. Electronic interfaces for differential capacitive sensors is an ideal text for academic staff and Masters/research students in electronic and microelectronic engineering.
This book was conceived as a laboratory on microhistory, an attempt to illustrate its main processes and advantages. Through the microhistorical approach the reader is off on an adventurous journey to discover an individual’s perspective, that of maestro Luigi Prisco who emigrated to the USA from the south of Italy. Luigi Prisco was a provincial musician and composer, born in 1857, who lived in Avellino, in Campania. In May 1902 Prisco joined millions of people in emigrating from southern Italy and the rest of the country to the United States, one more droplet in the immense river of Italian migration. Luigi Prisco’s personal correspondence with his mentor and friend Senator Donato Di Marzo (1840–1911) provides us with a precious insight into the aspirations and desires of a man who, through his actions, brought radical change to his life. Maestro Prisco’s letters are an interesting and insightful form of self-narration, which can only be fully understood using a microhistorical approach. The study of these letters is particularly valuable in highlighting the relationship between society and the intimate life of an individual, but also in underlining the active role that Prisco as an individual was able to play. This volume will be of great use to scholars interested in microhistory, the history of migrations, the history of ‘the self’ and in the development of theoretical approaches and methodologies when using letters as sources in interdisciplinary historical research.
