Realization of resistorless floating inductor using modified CDTA

Prasad, Dinesh ; Haseeb, Zainab ; Mainuddin, Prof. ; Akram, Md. W.


This paper briefly introduces a modified current differencing trans-conductance amplifier (M-CDTA) and its application in the simple realization of floating inductors. The proposed inductor is positive floating and lossless type offering the advantage of wider frequency bandwidth. The resulting equivalent inductance has been realized using one M-CDTA and one grounded capacitor and its inductance value can be adjusted electronically by proper tuning of the bias current. Results demonstrating the behavior of the circuit and its application confirming the theoretical analysis are verified through PSPICE simulations.
