The paper presents an electrical model developed for Pspice simulation of the behavior of the magnetic amorphous wires (MAW) working under the Giant Magnetoimpedance (GMI) effect. The model was developed in order to facilitate the design of the signal conditioning circuitry belonging to the new category of transducers whose sensitive element is based on the GMI effect. The model is a complex one, owing to the fact that the effect is influenced by many internal or external factors, whose actions have to be taken into consideration. In the paper, an example on how the model can be applied to simulate a Colpitts oscillator is given next to its presentation and analysis.
