Abstract
This work presents an electronically tunable series RC impedance simulator circuit by means of the recently introduced active element, called voltage differencing buffered amplifier (VDBA). The proposed circuit employs only two VDBAs and one grounded capacitor, which is canonic in the number of components. The simulated equivalent element values can be tuned electronically through the VDBA transconductance gain. The circuit also does not require any component-matching conditions. The non-ideal gain effects of the VDBA on the simulated capacitance value are also evaluated and discussed. PSPICE simulations, which are in a close agreement with the analytical calculations, are included.
