New Frequency Dependent Negative Conductance Simulator employing VDTAs and Grounded Capacitances

This research article proposes a new grounded frequency dependent negative conductance (FDNC) simulator. The presented simulator is designed by employing two voltage differencing trans-conductance amplifiers (VDTAs) along with two grounded capacitances. The presented FDNC simulator enjoys electronic controllability of realized negative conductance with no component matching constraints and exhibits excellent behavior under non-ideal conditions with low active/passive sensitivity indexes. The working of presented FDNC simulator has been verified by some voltage mode filter design examples. The performance of presented circuits has been verified by PSPICE simulations.
