Abstract: A charge-pump device receives two complementary driving signals and a DC signal that are applied to a charge-pump stage containing a full-wave rectifier bridge configured to deliver a DC output signal. The bridge includes active switches controllable by control signals present at two control nodes. The charge-pump device further receives complementary auxiliary signals that are respectively synchronous with the complementary driving signals but have faster edges. Two resistive capacitive filters filter the complementary auxiliary signals to generate control signals at the two control nodes for controlling actuation of the active switches in the bridge.

Abstract: A support substrate has a mounting face and a connection face opposite to the mounting face. An electronic chip is mounted to the mounting face and a matrix of connectors is mounted to the connection face. The support substrate includes an interconnection structure formed by a pair of conductive interconnection tracks that electrically connect the electronic chip to the matrix of connectors and circulate differential signals. The two interconnection tracks of the pair of conductive interconnection tracks extend facing each other at different depths of the support substrate. An isolation structure in the support substrate laterally isolates the pair of conductive interconnection tracks. Isolation plates above and below the pair of conductive interconnection tracks provide further isolation.

Abstract: The system-on-chip includes at least one microprocessor domain including a microprocessor and at least one resource; and a resource isolation system including a filtering circuit for each resource and configured to detect a security, privilege and compartmentalization access rights violation for the resource, by transactions arriving at the resource. The filtering circuit is configured, in the event of a violation of at least one access right to the resource by a transaction, to generate a first error signal representative of the violated access right to the resource, and a second error signal representative of at least one access right of this transaction.

Abstract: A method is for detecting one or more objects in a detection zone using a time-of-flight sensor. The method includes emitting optical radiation via the emission circuitry of the sensor and subsequently capturing the reflected optical radiation using the reception circuitry. This captured radiation is quantified in terms of photons, and measurement circuitry determines both the amount of these photons and the distance from the sensor to the object(s). An analysis of the photon count, combined with the calculated distance, is used to determine the presence or absence of objects within the detection zone.
