The Influence of Anti-Pad Array on the Inductance of PCB Power Net Area Fill
A low impedance power distribution network (PDN) is essential for the functionality of high speed printed circuit boards. A pre-layout impedance calculation can avoid time consuming changes on the design during post-layout stage. Design curves for inductance estimation are convenient to use in pre-layout stage. However, the high density voids on the power plane, which is caused by the anti-pads, are not considered in those design curves. This short paper discussed the extra inductance caused by the anti-pads, in two common situations.
