Abstract(in English) | Three-terminal capacitors have been investigated as bypass capacitors of the noise filter, because residual inductance of the three-terminal capacitors is smaller than that of conventional two-terminal capacitors. In this paper, we show the availability of numerical technique which can predict noise suppression effect using the three-terminal capacitors First, we explain the construction of equivalent circuit of the three-terminal capacitor, by subtracting the parasitic inductance of patterns and vias on test boards from the measured results. Next, the noise suppression effect of evaluation boards is analyzed by electromagnetic analysis with the equivalent circuits of the three-terminal capacitors. The analyzed results identical with the measured results quantitatively. Finally, we show residual inductance of the three-terminal capacitors is 1/10 of conventional two-terminal capacitors, and the noise suppression effect of a three-terminal capacitor is equivalent to four parallel connected conventional two-terminal capacitors. |
