本文介绍了在CMOS平台上实现高效、完全集成的DC-DC转换和调节功能的进展。在提供电感器为基础的方法和开关电容器之间的比较评估，介绍审查的开关技术的利用效率和使用和实施的无源器件的显着特点。分析的结论指向开关电容器（SC）的方法的强大优势，开关利用率和更高的能量密度的电容器与电感器。最近开发和出版的集成DC-DC转换器的电感为基础的SC类型的审查证实了分析。
This paper provides a perspective on progress toward realization of efficient, fully integrated dc-dc conversion and regulation functionality in CMOS platforms. In providing a comparative assessment between the inductor-based and switched-capacitor approaches, the presentation reviews the salient features in effectiveness in utilization of switch technology and in use and implementation of passives. The analytical conclusions point toward the strong advantages of the switched-capacitor (SC) approach with respect to both switch utilization and much higher energy densities of capacitors versus inductors. The analysis is substantiated with a review of recently developed and published integrated dc-dc converters of both the inductor-based and SC types.
