Abstract
Actively simulated lossy series RL-type inductor with voltage differencing buffered amplifier (VDBA) is described. The proposed inductance simulator is simulated using one VDBA, one grounded capacitor and one floating resistor. The realized equivalent value of the simulator is electronically controllable by the transconductance parameter of the VDBA. The effect of the VDBA non-idealities on the realized equivalent resistance and inductance values is also investigated in detail. As an application, active second-order current-mode lowpass filter is designed using the proposed variable lossy inductance simulator. The results obtained from PSPICE simulation demonstrate a close agreement with the theory, and also confirm the workability of the proposed simulator and its filter application.
