When hardware is free, power is expensive! Is integrated power management the solution?

Abstract

In the last several years, significant efforts and advances have been made towards the CMOS integration of power converters. In this paper, an overview is given of what might be considered the next step in this domain: AC-DC conversion, efficient high-ratio voltage conversion, wide operating range and energy storage for energy scavenging. The main focus is on CMOS integration as this is the ultimate goal from any system integration point of view. Also, an overview of the state of the art will be discussed.
