Time domain analysis of a through hole via with time dependent skin effect model

Kevin Cai, George I. Costache

Open publisher page 1 citations

Abstract

This paper presents a transient simulation of a through hole via connecting transmission lines on both sides of a printed circuit board. The via is modeled by a lumped RLC equivalent circuit that takes into account the skin effect in the cylindrical conductor. In the analysis of the transmission line part, a new skin effect model accounting for the time dependent losses is included. A mathematical interface is established between discrete time domain solutions and a lumped element RLC circuit. Numerical results show reasonable response due to the through hole via.
