Abstract:
-This paper discusses the impedance characterization of inductive elements. The study aims to investigate the existence of fractional-order elements by conducting tests to determine their inductive behaviour. A test bed, consisting of a signal generator and voltage-to-current (V/I) converter, was designed to feed an alternating current (AC) signal to each device under test (DUT). The signal generator was implemented using XR-2206 to produce a sinusoidal signal at varying decade frequencies from 10Hz to 100 kHz. The V/I converter used an LM358 op-amp to convert the signal before it reaches the DUT. The impedance of each DUT is determined by taking the relationship between the voltage across the DUT and its input current. The magnitude of the impedance is drawn for each decade frequency and graphed. The impedance transfer function determines the fractional behaviour of the DUTs and is derived from the Magnitude vs. Frequency Plot.
