| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | High frequency currents flowing in power supply networks of an IC/LSI has been estimated by an EMC macro model. The high frequency currents due to the simultaneous switching noise of IC/LSI involving large amount of CMOS transistor is modeled with a linear equivalent circuit and current sources. The linear equivalent circuit decreased its accuracy in impedance due to parasitic capacitances causing anti-resonances in the power supply networks. This paper shows with results of experimental and numerical analysis that the parasitic capacitances on the package and printed circuit board cause the anti-resonance. The power supply network impedance were obtained experimentally by use of three evaluation boards with different parasitic capacitances. The parasitic capacitances of the boards were calculated numerically by high-frequency electromagnetic analysis software Sonnet. Impedance simulations by considering the parasitic capacitance shows that an appropriate connection of parasitic capacitances to the LECCS model can expand an available frequency range of the model beyond 1 GHz. |
