An integrated circuit composes a function block including a plurality of primitive cells of a plurality of types. A bypass capacitor is connected between a power supply line and a ground line in a particular primitive cell that receives a periodical signal. The bypass capacitor is adjacent to a particular gate circuit of those forming a primitive cell, and the particular gate circuit receives the periodical signal. In this integrated circuit, the impedance of the bypass capacitor in the primitive cell at high frequency is decreased so that the sum of the resistance and inductance components of the power supply line in the IC chip and the inductance component of the IC package may become greater than the impedance of the bypass capacitor at high frequency. As a result, the leakage current from the IC is decreased, thereby limiting the generation of EMI noise from the IC. |
