Preface:

Big data generated by the Internet of Things (IoT), healthcare, and the world wide web (WWW) are changing our lifestyle and our society. Small chips are enabling this change through data sensing, gathering, processing, storing and networking through wireless and wired connections. This explosive growth of electronic devices and their deployment in new applications have sparked an urgency to address their environmentally benign and sustainable energy needs. The spread of mobile computing and the IoT devices is limited by both battery life and form factor. Research in the field of power management circuits and systems in the last 5–10 years has explored integrated power management units with a small form factor, increased power density, and efficient performance over a wide range of output power in the quest for replacing and/or more efficiently operating with conventional rechargeable batteries and carbon-based sources. The book begins with a comparison between inductive and capacitive dc–dc converters in terms of their passive devices, amenability to integration, and efficiency at various load conditions. A hybrid inductive–capacitive converter is pro

posed for wide-range dynamic voltage scaling, with details on the static, dynamic performances and discussion of different loss mechanisms. Next, the design of singleinductor dual output (SIDO) and single inductor multiple output (SIMO) converters are covered in detail in Chapters 2 and 3, including the presentation of different design goals such as reducing the number of power switches and their associated power losses, extending the output current range, reducing ripple, and improving dynamic performance. Various control techniques are discussed to meet the different design goals with an emphasis on adaptive pseudo-continuous conduction mode (PCCM) detailed in Chapter 3. Design aspects of switched capacitor (SC) dc–dc converters are given in Chapters 4 through 6. While advantageous in terms of their integration potential, switched capacitor converters have been limited to lower power density applications in addition to lower efficiencies as the load moves away from optimum design conditions. Techniques such as quasi-SC converters, soft-charging or resonant SC converters, and recursive SC converters are detailed to address some of the aforementioned limitations. Chapters 7 and 8 present a different perspective on power management units through the use of GaAs pHEMTs for efficient high frequency switching converters. The details of device design, high-quality factor passives, and circuit design techniques tailored to GaAs technology are discussed in addition to reconfigurable output passive networks to maintain the high efficiency of GaAs converters over wider voltage and current ranges. Some of the circuit tech niques such as resonant gate drivers are compared in both GaAs and CMOS technologies as in Chapter 8. While many of the chapters are focused around several key publications in the field, rather than republishing the original papers, the authors have expanded the material to provide more background and breadth than the original publications. As such, the book would complement a graduate level course on power electronics integrated circuits.
