Abstract
An equivalent inductance circuit includes a feedback type integration circuit and a differential amplifying circuit. An input signal applied to an input terminal is integrated by the feed-back type integration circuit and, a signal according to a difference component between an integrated output signal and the input signal is outputted by the differential amplifying circuit. By feeding the difference signal back to the input terminal, an input impedance equivalently represents an inductance characteristic. Such equivalent inductance can be changed by a current from a variable current source which supplies the current to the differential amplifying circuit and, a change of the equivalent inductance shows an inverse proportional manner.
