This book describes synergetic innovation opportunities offered by combining the field of power conversion with the field of integrated circuit (IC) design. The authors demonstrate how integrating circuits enables increased operation frequency, which can be exploited in power converters to reduce drastically the size of the discrete passive components. The authors introduce multiple power converter circuits, which are very compact as result of their high level of integration. First, the limits of high-power-density low-voltage monolithic switched-capacitor DC-DC conversion are investigated to enable on-chip power granularization. AC-DC conversion from the mains to a low voltage DC is discussed, enabling an efficient and compact, lower-power auxiliary power supply to take over the power delivery during the standby mode of mains-connected appliances, allowing the main power converter of these devices to be shut down fully.

The chapters in this edited book are written by some authors who have presented very high quality papers at the 2015 International Symposium of Next-Generation Electronics (ISNE 2015) held in Taipei, Taiwan. The ISNE 2015 was intended to provide a common forum for researchers, scientists, engineers, and practitioners throughout the world to present their latest research findings, ideas, developments, and applications in the general areas of electron devices, integrated circuits, and microelectronic systems and technologies. The scope of the conference includes the following topics: A. Green Electronics B. Microelectronic Circuits and Systems C. Integrated Circuits and Packaging Technologies D. Computer and Communication Engineering E. Electron Devices F. Optoelectronic and Semiconductor Technologies The technical program consisted of 4 plenary talks, 23 invited talks, and more than 250 contributed oral and poster presentations. Plenary speakers were recognized experts in their fields, and their talks focused on leading-edge technologies including: "The Future Lithographic Technology for Semiconductor Fabrication" by Dr. Alek C. Chen, Asia ASML, Taiwan. "Detection of Single Traps and Characterization of Individual Traps: Beginning of Atomistic Reliability Physics" by Prof. Toshiaki Tsuchiya, Shimane University, Japan. "The Art and Science of Packaging High-Coupling Photonics Devices and Modules", by Prof. Wood-Hi Cheng, National Chung-Hsing University, Taiwan. "Prospect and Outlook of Electrostatic Discharge (ESD) Protection in Emerging Technologies", by Prof. Juin J. Liou, University of Central Florida, USA. After a rigorous review process, the ISNE 2015 technical program committee has selected 10 outstanding presentations and invited the authors to prepare extended chapters for inclusion in this edited book. Of the 10 chapters, five are focused on the subject of electronic devices, and the other covers the circuit designs for various applications. The authors are working at the academia in Austria, United States, Korea, and Taiwan. The guest editors would like to take this opportunity to express our sincere gratitude to all the members of the ISNE 2015 technical program committees for reviewing the papers and selecting the manuscripts for the edited book. We also thank all the authors for their valuable and excellent contributions to the book.

Low-Power CMOS Wireless Communications: A Wideband CDMA System Design focuses on the issues behind the development of a high-bandwidth, silicon complementary metal-oxide silicon (CMOS) low-power transceiver system for mobile RF wireless data communications. In the design of any RF communications system, three distinct factors must be considered: the propagation environment in question, the multiplexing and modulation of user data streams, and the complexity of hardware required to implement the desired link. None of these can be allowed to dominate. Coupling between system design and implementation is the key to simultaneously achieving high bandwidth and low power and is emphasized throughout the book. The material presented in Low-Power CMOS Wireless Communications: A Wideband CDMA System Design is the result of broadband wireless systems research done at the University of California, Berkeley. The wireless development was motivated by a much larger collaborative effort known as the Infopad Project, which was centered on developing a mobile information terminal for multimedia content - a wireless `network computer'. The desire for mobility, combined with the need to support potentially hundreds of users simultaneously accessing full-motion digital video, demanded a wireless solution that was of far lower power and higher data rate than could be provided by existing systems. That solution is the topic of this book: a case study of not only wireless systems designs, but also the implementation of such a link, down to the analog and digital circuit level.

Power consumption has become a major design consideration for battery-operated, portable systems as well as high-performance, desktop systems. Strict limitations on power dissipation must be met by the designer while still meeting ever higher computational requirements. A comprehensive approach is thus required at all levels of system design, ranging from algorithms and architectures to the logic styles and the underlying technology. Potentially one of the most important techniques involves combining architecture optimization with voltage scaling, allowing a trade-off between silicon area and low-power operation. Architectural optimization enables supply voltages of the order of 1 V using standard CMOS technology. Several techniques can also be used to minimize the switched capacitance, including representation, optimizing signal correlations, minimizing spurious transitions, optimizing sequencing of operations, activity-driven power down, etc. The high- efficiency of DC-DC converter circuitry required for efficient, low-voltage and low-current level operation is described by Stratakos, Sullivan and Sanders. The application of various low-power techniques to a chip set for multimedia applications shows that orders-of-magnitude reduction in power consumption is possible. The book also features an analysis by Professor Meindl of the fundamental limits of power consumption achievable at all levels of the design hierarchy. Svensson, of ISI, describes emerging adiabatic switching techniques that can break the CV2f barrier and reduce the energy per computation at a fixed voltage. Srivastava, of AT&T, presents the application of aggressive shut-down techniques to microprocessor applications.
