Series Sensor Current Loop from a Generalized Impedance Converter Circuit with Reference Current Input

摘要

The paper describes the ability of the Generalized Impedance Converter (GIC) to work as a current-to-current converter. In its classical use GIC circuit was employed to simulate inductors in filters. Putting resistances in its structure and a current generator at its input, the GIC acts as a true current amplifier. The topology is analyzed obtaining DC properties and AC transfer functions. Experimental results are also shown demonstrating how GIC circuit with reference current input could implement a current loop to drive a series sensor connection.
