Abstract

This paper presents a technique to efficiently supply power over a wide power range using a fully integrated on-chip converter for dynamic voltage scaling (DVS) based applications. All components, including filter elements, are integrated on-chip. To achieve high efficiency the converter adaptively switches between different modes of operation by detecting the output current. The design, implemented in the IBM 130nm CMOS technology achieves a peak efficiency of 74.5% and can operate over a 450X power range (0.6mW to 266mW). This represents the best reported power range for a high-efficiency fully integrated on-chip power converter.
