Patent ID: 8650526

Claim:
A method for creating an equivalent circuit for a three-terminal capacitor including first, second, third and fourth electrodes, a first capacitor conductor connected between the first electrode and the second electrode, and a second capacitor conductor connected between the third electrode and the fourth electrode, the method comprising the steps of: creating an equivalent circuit including: a first line that connects the first electrode to the second electrode; a second line that connects the third electrode to the fourth electrode; a third line that includes a first capacitor component and that connects the first line to the second line; a first circuit component that includes at least one of a first inductor component and a first resistor component provided between a connection portion between the second line and the third line and the third electrode; and a second circuit component that includes at least one of a second inductor component and a second resistor component provided between the connection portion between the second line and the third line and the fourth electrode; and calculating values of the first capacitor component, the first inductor component, the first resistor component, the second inductor component, and the second resistor component when a difference between a first S parameter acquired from the equivalent circuit and a certain second S parameter is smaller than a certain value.
