Abstract

This paper demonstrated crosstalk suppressions of three-type noise suppressors using Co-Zr-Nb, Ni-Fe, and (Co-Pd)-CaF₂ soft magnetic films. Simple two parallel microstrip lines (MSLs) with the line width of 95 μm were fabricated and used as a test bench to evaluate crosstalk suppression. The films placed on the MSLs suppressed both near- and far-end crosstalks around effective ferromagnetic resonance (FMR) frequencies. By applying an external magnetic field to the films, the FMR contribution to crosstalk suppressions was clarified. These results indicate usefulness of the magnetic films to increase a design freedom of IC chips and packages.
