• High-frequency currents flowing from power terminals of an IC/LSI onto power/ground planes of a digital printed circuit board can generate a great amount of electromagnetic noise. A powercurrent model of an IC/LSI for EMI simulation was proposed in our previous studies. A high-speed simulation algorithm of EM radiation due to resonance of the power/ground planes in a PCB was also developed. This paper describes the mechanism and quantitative effect of reducing high frequency currents on power/ground terminals by embedding a decoupling inductor and/or a bypass capacitor in an IC/LSI package. Furthermore, the internal decoupling effect on suppressing EMI radiated from the board is verified in both the simulations and measurements.
