Power is receiving a mounting share of attention. Innovation, fueled by the information and internet age, poses new challenges for electronic systems across a spectrum of applications. Mobile devices continue to break new frontiers of functional integration. Phones are now your email, social networking interface, video and music player, gaming device, camera, GPS, and more – all rolled into one.  Yet the smart phone must survive through the day, and hopefully longer, without having to recharge the battery. Data centers and cloud computing grapple with power and carbon footprints as they move and process incredible amounts of data back and forth, consuming electricity to the order of 1-2% of the total that the entire world consumes. Advances in fabrication technology have made it possible for processors and system-on-chips (SoCs) to boast of over three-billion transistors, also pushing the limits of power density, integrity and reliability.
