A METHOD OF OPERATING LC SENSORS, CORRESPONDING SYSTEM AND APPARATUS

摘要

In one embodiment, an inductive/LC sensor device includes:
- energy accumulation means (C ref ) for accumulating excitation energy,
- an LC sensor (10) configured for oscillating energized by energy accumulated,
- an energy detector (12) for detecting the energy accumulated on the energy accumulation means (C ref ) reaching a charge threshold, and
- at least one switch (S1, S2) coupled with the energy detector (12) for terminating accumulating excitation energy for the sensor (10) on the energy accumulation means (C ref ) when the charge threshold is detected having been reached by the energy detector (12).
