<p>The present invention provides a semiconductor integrated circuit including a plurality of different primitive cells constituting a functional block, characterized in that the semiconductor integrated circuit includes a bypass capacitor electrically connected between a wire electrically connected to a power source and a grounded wire in a specific primitive cell into which a periodically varying signal is input, and the bypass capacitor is located adjacent to a gate circuit to which the periodically varying signal is input, among a plurality of gate circuits constituting the primitive cells. In accordance with the semiconductor integrated circuit, an impedance of the bypass capacitor arranged in a primitive cell is reduced in a high frequency band, and resultingly, a total of a resistance of a wire electrically connected to a power source, in IC chip, an inductance in IC chip, and an inductance of IC package is greater than an impedance of the bypass capacitor in a high frequency band. This ensures reduction in leakage of a high frequency current generated in IC, to outside of IC. As a result, it is possible to suppress EMI noises generated in IC. <IMAGE></p> |
