This peer-reviewed book explores the technologies driving broadband internet connectivity in the fourth industrial revolution (Industry 4.0). It particularly focuses on potential solutions to introduce these technologies in emerging markets and rural areas, regions that typically form part of the digital divide and often have under-developed telecommunications infrastructures, a lack of skilled workers, and geographical restrictions that limit broadband connectivity. Research shows that ubiquitous internet access boosts socio-economic growth through innovations in science and technology, with the common goal of bringing positive change to the lives of individuals. Fifth-generation (5G) networks based on millimeter-wave (mm-wave) frequency information transfer have the potential to provide future-proof, affordable and sustainable broadband connectivity in areas where previous-generation mobile networks were unable to do so. This book discusses the principles of various technologies that enable electronic circuits to operate at mm-wave frequencies. It examines the importance of identifying, describing, and analyzing technology from a purely technological standpoint, but also acknowledges and investigates the challenges and limitations of introducing such technologies in emerging markets. Presenting recent research, the book spearheads participation in Industry 4.0 in these areas.

This peer-reviewed book explores the methodologies that are used for effective research, design and innovation in the vast field of millimeter-wave circuits, and describes how these have to be modified to fit the uniqueness of high-frequency nanoelectronics design. Each chapter focuses on a specific research challenge related to either small form factors or higher operating frequencies. The book first examines nanodevice scaling and the emerging electronic design automation tools that can be used in millimeter-wave research, as well as the singular challenges of combining deep-submicron and millimeter-wave design. It also demonstrates the importance of considering, in the millimeter-wave context, system-level design leading to differing packaging options. Further, it presents integrated circuit design methodologies for all major transceiver blocks typically employed at millimeter-wave frequencies, as these methodologies are normally fundamentally different from the traditional design methodologies used in analogue and lower-frequency electronics. Lastly, the book discusses the methodologies of millimeter-wave research and design for extreme or harsh environments, rebooting electronics, the additional opportunities for terahertz research, and the main differences between the approaches taken in millimeter-wave research and terahertz research.

This book is the first standalone book that combines research into low-noise amplifiers (LNAs) with research into millimeter-wave circuits. In compiling this book, the authors have set two research objectives. The first is to bring together the research context behind millimeter-wave circuit operation and the theory of low-noise amplification. The second is to present new research in this multi-disciplinary field by dividing the common LNA configurations and typical specifications into subsystems, which are then optimized separately to suggest improvements in the current state-of-the-art designs. To achieve the second research objective, the state-of-the-art LNA configurations are discussed and the weaknesses of state-of the art configurations are considered, thus identifying research gaps. Such research gaps, among others, point towards optimization - at a systems and microelectronics level. Optimization topics include the influence of short wavelength, layout and crosstalk on LNA performance. Advanced fabrication technologies used to decrease the parasitics of passive and active devices are also explored, together with packaging technologies such as silicon-on-chip and silicon-on-package, which are proposed as alternatives to traditional IC implementation. This research outcome builds through innovation. Innovative ideas for LNA construction are explored, and alternative design methodologies are deployed, including LNA/antenna co-design or utilization of the electronic design automation in the research flow. The book also offers the authors' proposal for streamlined automated LNA design flow, which focuses on LNA as a collection of highly optimized subsystems.

This book provides a system-level approach to making packaging decisions for millimeter-wave transceivers. In electronics, the packaging forms a bridge between the integrated circuit or individual device and the rest of the electronic system, encompassing all technologies between the two. To be able to make well-founded packaging decisions, researchers need to understand a broad range of aspects, including: concepts of transmission bands, antennas and propagation, integrated and discrete package substrates, materials and technologies, interconnects, passive and active components, as well as the advantages and disadvantages of various packages and packaging approaches, and package-level modeling and simulation. Packaging also needs to be considered in terms of system-level testing, as well as associated testing and production costs, and reducing costs. This peer-reviewed work contributes to the extant scholarly literature by addressing the aforementioned concepts and applying them to the context of the millimeter-wave regime and the unique opportunities that this transmission approach offers.

This book provides a methodological understanding of the theoretical and technical limitations to the longevity of Moore's law. The book presents research on factors that have significant impact on the future of Moore's law and those factors believed to sustain the trend of the last five decades. Research findings show that boundaries of Moore's law primarily include physical restrictions of scaling electronic components to levels beyond that of ordinary manufacturing principles and approaching the bounds of physics. The research presented in this book provides essential background and knowledge to grasp the following principles: Traditional and modern photolithography, the primary limiting factor of Moore's law Innovations in semiconductor manufacturing that makes current generation CMOS processing possible Multi-disciplinary technologies that could drive Moore's law forward significantly Design principles for microelectronic circuits and components that take advantage of technology miniaturization The semiconductor industry economic market trends and technical driving factors The complexity and cost associated with technology scaling have compelled researchers in the disciplines of engineering and physics to optimize previous generation nodes to improve system-on-chip performance. This is especially relevant to participate in the increased attractiveness of the Internet of Things (IoT). This book additionally provides scholarly and practical examples of principles in microelectronic circuit design and layout to mitigate technology limits of previous generation nodes. Readers are encouraged to intellectually apply the knowledge derived from this book to further research and innovation in prolonging Moore's law and associated principles.
