A VDCC-Based Grounded Passive Element Simulator/Scaling Configuration with Electronic Control

In this research paper, a new circuit configuration which can work like a grounded impedance simulator/grounded impedance scaling circuit has been proposed. The proposed circuit can simulate electronically controllable grounded resistance/capacitance/inductance/FDNC and can also work like a grounded impedance multiplier circuit, which can scale the value of arbitrary grounded impedance with an electronically tunable multiplication factor. The presented circuit employs two voltage difference current conveyors along with four grounded passive elements. The employment of grounded passive elements makes this realization eligible for monolithic integration. The proposed circuit does not require any matched passive elements. Behavior of the proposed configuration under nonideal environment is found un-deviated. The mathematical analysis of the proposed configuration has been verified by simulating under PSPICE TSMC 0.18 µm simulation environment.
