This book describes the design and realization of analog fractional-order circuits, which are suitable for on-chip implementation, capable of low-voltage operation and electronic adjustment of their characteristics. The authors provide a brief introduction to fractional-order calculus, followed by design issues for fractional-order circuits of various orders and types. The benefits of this approach are demonstrated with current-mode and voltage-mode filter designs. Electronically tunable emulators of fractional-order capacitors and inductors are presented, where the behavior of the corresponding chips fabricated using the AMS 0.35um CMOS process has been experimentally verified. Applications of fractional-order circuits are demonstrated, including a pre-processing stage suitable for the implementation of the Pan-Tompkins algorithm for detecting the QRS complexes of an electrocardiogram (ECG), a fully tunable implementation of the Cole-Cole model used for the modeling of biological tissues, and a simple, non-impedance based measuring technique for super-capacitors.

Circuit design is not only relevant for electrical engineering. It can also be applied to interdisciplinary projects that require electrical input, output, or control, such as robotics, biomedical devices, renewable energy, and smart systems. Through interdisciplinary projects, the designer must understand the project goals and requirements, as well as the roles of other team members. Therefore, communication with collaborators is essential, as is the use of common standards and tools to ensure compatibility. In the framework of this CASS Seasonal School call, a 2-day school on "e;Interdisciplinary Applications of Circuits and Systems"e; was organized during October 16-17, in the Conference and Cultural Center of the University of Patras, Greece. At this educational event, basic and advanced issues on design methodologies targeting on interdisciplinary applications were presented, including the following: circuits and systems in biology/biomedicine, in agriculture, in cryptography, in control systems, in chaos, in RF applications, in Internet of Things (IoT) systems, in quantum computing, as well as the employment of artificial intelligence and machine learning techniques for designing circuits.In this book the following are introduced: Chaotic oscillators and their real-world applications, the basic principles of the PID controllers followed by application design examples Applications of circuits in agriculture, the employment of artificial intelligence (AI) and machine learning (ML) techniques for design The design challenges and innovative solutions for energy harvesting for wearable and implantable devices Medical and health applications of biosensing circuits and systems Cryptographic hardware and embedded systems Computer vision and deep learning techniques for electronic circuit inspection Cryo-CMOS integrated circuits for scalable quantum computing Energy-efficient analog circuits and systems for emerging RF applications.
