Modeling circuit of high-frequency device and modeling method thereof

Abstract

There are provided a modeling circuit of a high-frequency device capable of providing a more accurate modeling circuit having a higher-order resonance by dividedly modeling an overlap zone and a non-overlap zone of the high-frequency device, and a modeling method thereof. The modeling circuit of a high-frequency device, which comprises an overlap zone where the two electrodes are overlapped with each other, a non-overlap zone where the overlap zone is absent between the two electrodes, the overlap and non-overlap zones being formed by stacking two or more electrodes on top of each other in a constant distance, and terminations electrically coupled with some parts of the two electrodes, comprises a first circuit block comprising a first capacitor and a first conductor that model the overlap zone of the high-frequency device on the basis of coupled transmission line theory; and a second circuit block comprising a first inductor and a first register that model the overlap zone of the high-frequency device on the basis of coupled transmission line theory and model the non-overlap zone and the terminations of the high-frequency device on the basis of a Series RL model.
