去耦电路的设计时，往往会使用目标阻抗计算的方法。那么关于VRM的等效电感如何界定?Altera给的工具中开关电源为20nh，LDO为10nh。这个数值有没有达人测试过?
Get a copy of Larry Smith's paper : "Power Distribution System Design Methodology and
Capacitor Selection for Modern CMOS Technology"
This is the original paper that talked about VRM modeling and its parameter calculation. Most of PI tools use the formula and parameters he gave in the paper. You can find the paper through Google search.
