VDBA-based floating inductance simulator with a grounded capacitor

This study presents the resistorless floating inductance simulator circuit based on employing voltage differencing buffered amplifier (VDBA) as new active component. The proposed floating inductance simulator circuit uses two VDBAs and only one grounded capacitor, which is suitable for integrated circuit design. The resulting equivalent inductance value of the proposed simulator can be tuned electronically through the transconductance parameter of the VDBA. As application example, the second-order RLC bandpass filter has been simulated using the proposed tunable floating inductance simulator. The simulation results using standard 0.35 μm BiCMOS process model are included to verify the theoretical analysis.
