This book provides a comprehensive introduction to the current status and future trends of materials and component design for fifth-generation (5G) wireless communications and beyond. Necessitated by rapidly increasing numbers of mobile devices and data volumes, and acting as a driving force for innovation in information technology, 5G networks are broadly characterized by ubiquitous connectivity, extremely low latency, and very high-speed data transfer. Such capabilities are facilitated by nanoscale and massive multi-input multi-output (MIMO) with extreme base station and device densities, as well as unprecedented numbers of antennas. This book covers semiconductor solutions for 5G electronics, design and performance enhancement for 5G antennas, high frequency PCB materials and design requirements, materials for high frequency filters, EMI shielding materials and absorbers for 5G systems, thermal management materials and components, and protective packaging and sealing materials for 5G devices.

Flexible devices are gradually emerging as an alternative viable low-cost user-friendly technology for wearable health care services in different fields. Some of the attractive features of flexible devices are the integration of multiple sensing units with electronic circuits for any planar and non-planar mounting surfaces. With the advancement of flexible technologies, now the devices can be fabricated with superior response characteristics comparable to the conventional silicon IC technology. The purpose of the present book is to provide the readers with a single platform to develop a system using flexible sensors integrating with interfacing/signal conditioning, data conversion and communication circuits. During the last decade, soft robotics has seen an immense amount of growth due to its attractive characteristics, such as environmental adaptability, owing to the flexible structures employed, and operational safety for users, providing a promising human–machine interaction environment. To realize a soft robotic system, smart integration of several subsystems such as sensors, signal conditioning circuits, processors and software, actuators, and control and feedback mechanisms are needed.

As CMOS technology advances, circuits are exposed to various noise sources that impact circuit performance and reliability in nanometerscale integrated circuits. The reliability of the integrated circuits is being severely challenged, as many previously negligible noise effects are becoming more prominent, causing significant performance and reliability degradations of nanometer integrated circuits. Various noise sources exist in a nanometer circuit including crosstalk noise induced by signal switching on neighboring wires, power supply noise on power grid lines due to simultaneous switching events, substrate coupling noise, noise due to process and environmental variations, thermal noise and radiation-induced soft errors. The impacts of these noise sources are far more severe for clock lines since clock signal controls the data processing.
