摘要
An energy harvesting interface receives an electrical signal from an inductive transducer and outputs a supply signal. An input branch includes a first switch and a second switch connected in series between a first input terminal and an output terminal, and further a third switch and a fourth switch connected 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.
