摘要：

This paper shows a realization of circuit functions (such as a voltage transfer function, a transfer immitance, a driving-point immitance) with s(a) (-1 < alpha <1) characteristics. The circuit shown in this paper is realized by cascaded connection of a finite number of two-port networks consisting of operational transconductance amplifiers(OTAs) and capacitors. By changing the value of conductance of OTAs, changeable characteristic with respect to alpha is obtained. The value of alpha can be changed by adjusting the controlling current of OTAs.
