摘要

本文从效率、输出纹波和负载暂态响应等方面对传统线性辅助变换器和基于新型ab类LDO稳压器代替传统线性稳压器的LDO辅助变换器进行了全面的研究和比较。新结构减少了输入和输出电压之间的差异以及降压转换器的开关频率，从而提高了功率效率，这是电池供电设备(如生物医学植入物和能量收集应用)的电源管理系统所需要的。对比分析结果在0.18 μm CMOS工艺的HSPICE中得到验证。

LDO-assisted vs. linear-assisted DC/DC converters: A comprehensive study and comparison

This paper deals with a comprehensive study and comparison on the conventional linear-assisted converter and a new structure named, LDO-assisted converter based on a new class-AB LDO regulator instead of the conventional linear one, in terms of efficiency, output ripple, and load transient response. The new structure reduces difference between input and output voltages and also switching frequency of the buck converter, corresponding to higher power efficiency, desired for power management systems of battery operated devices like biomedical implants and energy harvesting applications. A comparison analysis is done and the results are validated in HSPICE in a 0.18 μm CMOS process.
