Abstract
A CMOS IC device operating at a frequency of 300 MHz or higher includes a power supply wiring for interconnecting one of circuit elements and a power supply pad, and a phase-shifting split wiring connected to the power supply wiring and not directly connected to any circuit elements, only for producing a noise phase difference between noises on the power supply wiring and the phase-shifting split wiring. A signal entering from the phase-shifting split wiring has a phase different from the phase of a signal transmitted on the power supply wiring to thereby reduce spike noises.
