Abstract
This paper proposes a circuit configuration for the realization of a four-terminal floating nullor (FTFN) with electronically tunable current gain. It mainly consists of an op amp in input together with two complementary current mirrors with controlled gain and two standard improved Wilson current mirrors. The validity of the performance of the scheme is verified through PSPICE simulation results. Some example applications in the design of the proposed tunable FTFN as a tunable active element show that the circuit properties can be varied by electronic means are also included.
