A novel design of active inductors based on current controlled voltage sources

Abstract

This brief presents a new structure of active inductors. These synthetic inductors are designed using current controlled voltage sources. The signal flow graph method is used for this purpose. For the practical realization, operational transresistance amplifiers (OTRAs) are replicated using current conveyors. The proposed inductors have very interesting properties because the value of its inductance is proportional to the product of the parameter of the OTRAs (rm1rm2) and thus, small capacitor values can be used. Current conveyor based simulated inductors are presented and SPICE simulations are given to show the viability of the proposed synthesis technique.
