Abstract
A resonant circuit includes a first inductor and a first capacitor which define a first series circuit and a second inductor connected in parallel to the first series circuit. The first inductor and the second inductor are coupled via a magnetic field in a direction in which magnetic fluxes passing through the inductor and the second inductor strengthen each other to effectively increase steepness in a transient band.
