Abstract

This work presents a switched-capacitor power converter (SCPC) with a power density of 38.6mW/mm2 at 81% efficiency and 3.8mV output voltage ripple (ΔV0) in baseline 90nm CMOS. The design implements two different conversion ratios to maximize efficiency for a wide range of input voltages, and the use of 41 phases results in a very low output voltage ripple and low input current spikes.
41相开关电容功率变换器,输出纹波3.8mV,效率81%
本研究提出了一种开关电容功率转换器(SCPC),其功率密度为38.6mW/mm2,效率为81%,输出电压纹波为3.8mV (ΔV0)。该设计实现了两种不同的转换比率,以在宽范围的输入电压下最大限度地提高效率,并且使用41相导致非常低的输出电压纹波和低输入电流尖峰。
