Abstract
An integrated circuit includes an amplifier for amplifying input electric power having a predetermined frequency determined depending on an application and a series capacitor connected to an output side of the amplifier and becoming a conductive state with respect to the electric current having the predetermined frequency but an open state with respect to the electric current having a frequency that is an odd multiple of the predetermined frequency. In the integrated circuit, the frequency that is the odd multiple thereof is processed by only the capacitor.
