Abstract
To design an impedance transformation circuit, a transformer ratio of a transformer circuit is determined according to an impedance ratio. A coupling coefficient between a first inductance element and a second inductance element, an inductance of the first inductance element, and an inductance of the second inductance element are determined. A shape of the second inductance element is determined. A shape of the first inductance element is determined such that the first inductance element includes at least two layers of loop conductors, and an interlayer distance between the loop conductors is determined such that an inductance value of the first inductance element is a desired value.
