The filter proposed in this paper has an advantage of higher the frequency response and better selectivity against the classical band pass filter.A active circuit current feedback operational amplifier (CFOA) has been designed and it uses the application of the implementing active filters, oscillators, rectifiers, and signal processing circuits. We observe that several active circuits have been proposed in the literature. In this study, we have proposed four inductance simulators that employ only one active circuit current feedback operational amplifier and three or four passive components. The first and fourth topologies are designed for series lossy inductance, whereas the second and third topologies are designed for lossless negative inductance simulators. A passive RLC filter is used to demonstrate the effectiveness of the proposed inductance simulators. The circuit design is synthesized using 130nm CMOS technology with ±3.3V power supply in cadence virtuoso and the simulation is done using Spectre and the results agree with the theoretical analysis.
