Abstract:
1. A semiconductor integrated circuit apparatus having at least one cell circuit integrated on a semiconductor substrate, wherein the cell circuit includes: at least one transistor; a capacitor having an electrode receiving an AC signal, having another electrode connected to a base of the transistor, and having a dielectric which is interposed between the electrode and said another electrode of the capacitor; and an inductor having a terminal to which a DC voltage is applied and having another terminal connected to the base of the transistor, wherein the inductor is formed of a spiral-shaped metal having two or more turns, the inductor is formed of a metal which is same as a metal of a collector electrode of the transistor and a metal of said another electrode of the capacitor, and said another terminal of the inductor is connected to the base of the transistor through said another electrode of the capacitor.
