Decoupling analysis with inductors

Good afternoon,

 

I have seen this topic mentioned before but I really wanted to have a full picture. Is it possible to include an inductor in your decoupling analysis?

I am analyzing the VDD pin of an IC and the power source is a 3V3 net. At the moment,  I can only get to carry out an analysis of the decoupling after the inductor (only C3 and C4 are being taken into account). However I would really want to see how the C1/C2 improves the impedance at lower frequencies. Can this be done?

Thanks in advance,

Xenxo
