Abstract

Un induttore planare a film spesso viene costruito secondo una geometria specifica con tecnica tradizionale. Tale dispositivo viene quindi tarato in modo funzionale per realizzare la sintonia del circuito in cui è montato, variando la geometria dell'induttore stesso tramite incisione laser.(Fig. 2).A planar film inductor is often built according to a specific geometry with traditional technique. This device is then calibrated in a functional way to achieve the tuning of the circuit in which it is mounted, varying the geometry of the inductor itself by laser engraving (Fig. 2).
