| Abstract(in English) | The relationship between LSI operation modes and radiated emission were studied. Among operation modes, I/O buffer operation radiated a large amount of emission. In this mode, widely distributed high frequency currents and imbalance in each power and ground wiring pair were observed. LSI mounting area can be considered an opening from the electromagnetic viewpoint, though it has high density of high frequency currents. Measures should be taken at LSI mounting area. It has been verified by putting ferrite on LSl package and covering LSI package with copper plate having ground connections, which reduce the emission by approximately 7dB, 13dB respectively. |
