Functional and Consumption Analysis of Integrated Circuits Supplied by Inductive Power Transfer by Powering Modulation and Lock-in Infrared Imaging

The functionality and consumption of an RFID IC supplied by Inductive Power Transfer (IPT) has been non-invasively analyzed by IR thermography.The main aspects addressed in thiswork have been: the suitability study of the proposed modulation strategies, the characterization of the coupling between coils and its effects on the RFID blocks, the RFID IC functional analysis, and the dependence of the local energy consumption on the total power delivered to the die.
