Current Feedback Operation Amplifier Based on Floating Passive and Active Inductors in Filter Applications

Abstract

This paper proposes using current feedback operation amplifiers (CFOAs) as an active filter in creating floating passive and active inductance simulators is a versatile and efficient solution for circuit design. CFOAs are popular for their high slew rate and wide bandwidth which makes them ideal candidates for applications demanding rapid response time alongside high frequencies. It is possible to customize these simulated inductances for different design specifics by changing certain external resistor values. The circuit comprises a trio of CFOAs, an earthed capacitor and three resistors, thus making it quite simple to put into practice at a cheap price. Experiments and LTSPICE simulations have been conducted to examine the performance of the circuit, and closely confirmed theoretical expectations. In other words, this confirms the trustworthiness and preciseness of the introduced floating active inductance simulator. Voltage-mode band-stop filtering is one real-world scenario where this circuit is used. This indicates that our proposed technique can have more applications than one in circuit design. This is further proof that our idea can be used in other circuits as well. In conclusion, using CFOAs in active filters for building a grounded passive active inductance simulator is a solid and effective answer to circuit designers. This makes it an appealing choice for numerous applications because of its simplicity in designing the network as well as its high performance and customizability. Circuit design and application can be greatly improved if more study is done in this field.
