<p><P>PROBLEM TO BE SOLVED: To achieve a proper capacitor arrangement method when resonance occurs in a power plane in a printed circuit board in which a power plane and a ground plane are provided and the power plane and the ground plane are connected by a capacitor. <P>SOLUTION: The method is configured to suppress the resonance of the power plane in the printed circuit board in which the power plane and a ground plane are provided. A capacitor, in which an impedance at a resonance frequency of the power plane shows a minimum value, is installed at a point near the part, where resonance occurs, of the power plane so as to connect the power plane and the ground plane to each other. A resistor is connected in series to the capacitor. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
