    Abstract: A method of package-to-board impedance matching for high speed integrated circuits (ICs). Multiple solder balls are attached to an IC package. The IC package includes multiple conductive interconnect layers, where one of the conductive interconnect layers is coupled to one or more of the multiple solder balls. Multiple vias are coupled between different conductive interconnect layers. An inductive element is coupled between an interconnect lead and a via land in the conductive interconnect layer within the IC package. The physical layout dimensions of the inductive element are configured such that the inductive element provides an inductance value that is sufficient to offset a parasitic capacitance provided by the conductive interconnect layers and the solder balls. The inductive element may be a bond wire, an inductive interconnect, or a spiral interconnect.
