Abstract
There is provided a negative impedance converter, which has negative impedance conversion function by widening the available range of a generalized impedance converter. A generalized impedance converter is composed of two operational amplifiers Qand Qand four series-connected first to fifth impedance elements Zto Z. The four impedance elements included in the generalized impedance converter are all set as the same resistor R, and an impedance element Zis connected between the intermediate point B of the series-connected impedance elements and the ground. The magnitude of the impedance element Zis set smaller than that of load impedance element Z. By doing so, the input impedance Zbecomes negative, and the kind of the impedance is determined depending on the kind of the impedance elements Zand Z.
