尽管半导体技术不断进步，但功率转换电路和子组件仍然是各种性能和嵌入式计算应用中的主要瓶颈。本文回顾和讨论了一些基本的权衡和未来的前景，高密度无源元件，有源器件和电路架构，显示单片或毫米级功率转换的方向的承诺。这些趋势在最小功率损耗品质因数（FOM）中得到统一，该最小功率损耗品质因数可用于在无源元件（面积、能量存储和/或体积）的各种约束下比较DC-DC转换器。本文重点介绍了开关电容和混合谐振转换器，并概述了与有源和无源元件利用率和转换比相关的重要趋势和权衡。
Despite ongoing advances in semiconductor technologies, power conversion circuits and subcomponents remain a major bottleneck in a variety of performance and embedded computing applications. This paper reviews and discusses some of the fundamental tradeoffs and future prospects for high-density passive components, active devices, and circuit architectures that show promise in the direction of monolithic or mm-scale power conversion. These trends are unified in a minimum power loss figure of merit (FOM) that can be used to compare DC-DC converters under various constraints on passive components (area, energy storage, and/or volume). The paper highlights switched-capacitor and hybrid-resonant converters and outlines important trends and tradeoffs that relate to active- and passive-component utilization and conversion ratio.
