Abstract
In a semiconductor integrated circuit, a ground plane conductor is formed in a substrate to oppose to a conducting line formed on the substrate, so as to form a microstrip line. A decoupling capacitor is provided on the substrate and is electrically connected between the conducting line and the ground plane conductor so as to bypass a high frequency current component flowing through the conducting line to the ground plane conductor. Thus, the impedance of the conducting line is stabilized, and a path of a feedback current of a high frequency current component flowing through the conducting line is ensured by the ground plane conductor , so that a current loop is minimized, resulting in minimized electromagnetic noises radiated from the current loop.
