Abstract(in English) Package inductance of semiconductor devices and wiring inductance affect the switching and EMI characteristics of high-speed digital circuits. The inductance, L, causes ground bounce, and also switching delay. Therefore it is important to decrease L for stable operation. Moreover the lower inductance makes the Q of resonance in digital circuit, which lowers the peak height of EMI spectrum. It is illustrated from the point of view of electromagnetism and electronic circuit theory that to decrease the inductance one should pay attention not only to the self inductance L but to the effective inductance L_=L-M, where M is the mutual inductance.
