基于自谐振频率电容器种类的选择算法

摘要

为使PDN阻抗曲线能在一个较宽的频率范围内不超过目标阻抗曲线,对去耦电容器种类的选择至关重要。因此,提出了基于自谐振频率电容器种类的选择算法,该算法已经用于工程实际中,效果理想。%In order to make the impedance curve of PDN（Power Distribution Net） under the target impedance curve,the selection of decoupling capacitors is very important.This paper presents the selection algorithm of capacitor type based on SRF.This algorithm has been used in engineering practice with satisfactory results.
