摘要： An energy harvesting interface receives an electrical signal from an inductive transducer and supplies a supply signal. The interface includes an input branch with a first switch and a second switch connected together in series between a first input terminal and an output terminal. The interface further includes a third switch and a fourth switch connected together in series between a second input terminal and the output terminal. A first electrical-signal-detecting device, coupled across the second switch, detects a first threshold value of an electric storage current in the inductor of the transducer. A second electrical-signal-detecting device, coupled across the fourth switch, detects whether the electric supply current that flows through the fourth switch reaches a second threshold value lower than the first threshold value. The second threshold is derived from the electric storage current.
