Accurate Socket Modeling And Validation For SI/PI Applications Considering Contact Resistance

Abstract

In this paper, we propose an accurate socket modeling methodology for signal integrity and power integrity applications using a quasi-static EM solver. Contact resistance is considered since it is a non-negligible component in socket modeling. A Parallel Resonance Frequency (PRF) method is used to validate the EM model and verify the contact resistance. It is shown that a quasi-static solver can be used to extract S-parameter or RLGC parameters and construct an accurate equivalent model without port parasitic.
