该论文提出了一种名为“飞域”的DC-DC转换器,用于为Cortex-M0处理器供电,实现了90.8%的高效率。解决了现代SoC中多电源域需要全集成、高效率且支持大动态电流范围的DC-DC转换器的难题。
Modern SoC designs employed in battery-life-constrained mobile applications feature multiple power domains to dynamically scale power-performance tradeoffs in response to application demands. Since each power domain requires a DC-DC converter, and since low-power mobile applications are also typically areaconstrained, the employed DC-DC voltage regulators must: 1) be fully integrated, 2) support high efficiency across large dynamic current ranges spanning highpower active modes to low-power sleep modes where the overhead of complex control or multi-phasing is not feasible [1], and 3) support high power density to occupy minimal area overhead. Unfortunately, achieving both high efficiency and power density is difficult: integrated magnetic converters have limited efficiency and do not leverage CMOS scaling, while switched-capacitor (SC) converters suffer from fundamental power density-efficiency trade-offs due to ½C(ΔV)2fbased slow-switching-limit (SSL) losses.
