    An active lossy parallel type inductance simulator is proposed in this study. Only a single voltage differencing gain amplifier (VDGA) and a grounded capacitor are used in the proposed design. The realized equivalent resistance (Req) and equivalent inductance (Leq) can be adjusted electronically via the transconductance gain of the VDGA device. The influence of the non-idealities of the VDGA on the realized simulator is examined in detail. The suggested active inductance simulator is used to realize the second order voltage mode highpass filter, which is simulated using the PSPICE simulation program to ensure that it performs as expected.

    Abstract: Alternative circuit designs concerning the simulation of floating lossy inductors using voltage differencing buffered amplifiers (VDBAs) are described. The topologies proposed here require only three VDBAs and one capacitor to simulate a floating inductance with series and parallel resistance. The simulated equivalent elements, namely equivalent resistance (R<inf>eq</inf>) and equivalent inductance (L<inf>eq</inf>) are electronically controllable through the external bias currents of the VDBAs. The VDBA non-idealities including transconductance inaccuracy and voltage transfer error on the performance of the circuits has been discussed in detail. To support the theoretical analysis and demonstrate the practical workability of the proposed synthetic inductors, PSPICE simulation and experimental test results are also reported.

    This paper discusses the active-only electronically tunable floating lossless inductance simulator, which uses a single fully balanced-voltage differencing buffered amplifier (FB-VDBA) and one operational amplifier (OA). For this implementation, only integrated circuit packages with no external passive components are utilized. The synthetic equivalent inductance value is electronically adjustable via the transconductance gain of the FB-VDBA. Non-idealities of the active element have produced their effects. Using PSPICE with TSMC 0.25-mum CMOS parameter and the LM741 type OA, the performance of the proposed circuit and its application as a second-order voltage-mode lowpass filter is demonstrated. The numerical simulations closely matched the theoretical results.

    This paper reports four topologies, all simulating floating/grounded lossy inductors, using voltage differencing buffered amplifiers (VDBAs) as active elements. The simulated equivalent resistance and inductance values of the simulators can be adjusted electronically through the VDBA transconductance parameter. Non-ideal gain outcomes of the VDBA on the realized inductor circuits are finalized. The critical active and passive sensitivities are obtained to be low.
