摘要

本文提出了一种基于测量的数据处理方法,通过本体去耦电容器获得多电流元件的参数,用于电源完整性研究。为了测量开关电流时变引起的感应电压,研制了一种实验室自制的低成本电流探头。然后,引入后置数据处理程序,分离并获得多电流分量的参数。用其他方法对所得到的结果进行了验证。

Measurement of multiple switching current components through a bulk decoupling capacitor using a lab-made low-cost current probe
This paper presents a measurement-based data-processing approach to obtain parameters of multiple current components through a bulk decoupling capacitor for power integrity studies. A lab-made low-cost current probe is developed to measure the induced voltage due to the time-varying switching current. Then, a post data-processing procedure is introduced to separate and obtain the parameters of multiple current components. The results obtained by the proposed method are validated with other approaches.
