QUALITY FACTOR ESTIMATION OF AN INDUCTIVE ELEMENT

The present disclosure relates to a device (1') comprising: an inductive element (L) and a first capacitive element (C) series connected between a first node (200) and a second node (202); a first MOS transistor (T2) connected between the first node (200) and a third node (204) configured to receive a reference potential (GND), the second node (202) being coupled directly or via a second MOS transistor (T3) to the third node (204); a second capacitive element (Cl) connected between a fourth node (210) and an interconnection node (212) between the first capacitive element (C) and the inductive element (L); a current generator (214) configured to provide an AC current (I) to the fourth node (210); and a switch (IT) connected between the fourth node (210) and the third node (204) .
