Beschreibung
Zusammenfassung:	The variable capacitance device includes one or more of directional elements inserted between the third and fourth terminals that allow current to pass only in prescribed directions, such that a diagram formed of current paths from the third terminal to the fourth terminal for the plurality of third-terminal side resistors and the plurality of fourth-terminal side resistors when the third terminal is biased higher than the fourth terminal is line-symmetric to a diagram formed of current paths from the fourth terminal to the third terminal for the plurality of third-terminal side resistors and the plurality of fourth-terminal side resistors when the fourth terminal is biased higher than the third terminal, with respect to the serial chain of variable capacitance elements between the first and second terminals.
