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 onchip. 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.
