Abstract: An electronic device includes: a control terminal, which extends on a first face of a substrate; a first conduction terminal, which extends in the substrate at the first face of the substrate; a first insulating layer interposed between the control terminal and the first conduction terminal; a conductive path, which can be biased at a biasing voltage; and a protection element, coupled to the control terminal and to the conductive path, which forms an electrical connection between the control terminal and the conductive path and is designed to melt, and thus interrupt electrical connection, in the presence of a leakage current higher than a critical threshold between the control terminal and the first conduction terminal through the first insulating layer.

Abstract: In accordance with an embodiment, a pulse generator circuit includes: an LC resonant circuit coupled between a first node and a reference node; a first switch coupled between the first node and the reference node; a switching network comprising a second switch coupled between the first node and a respective drive node; and drive circuit having outputs coupled to the first switch and to the second switch of the switching network. The drive circuit configured to, in repeating cycles: close the first switch when a current flowing through an inductor of the LC resonant circuit increases during a resonant cycle, when the current flowing through the inductor reaches a threshold value, open the first switch, close the second switch of the switching network for a pulse duration time when the first switch is open, and open the second switch at an expiration of the pulse duration time.

Abstract: A MEMS sensor has at least a movable element designed to oscillate at an oscillation frequency, and an integrated measuring system coupled to the movable element to provide a measure of the oscillation frequency. The measuring system has a light source to emit a light beam towards the movable element and a light detector to receive the light beam reflected back from the movable element, including a semiconductor photodiode array. In particular, the light detector is an integrated photomultiplier having an array of single photon avalanche diodes.
