Patent number: 11022991Abstract: An electrical device includes a power supply circuit configured to provide a first voltage and a second voltage, and a first verification circuit configured to derive a first and a second internal voltage from the first voltage, to compare the first and second internal voltages, and to generate a first output signal based on the comparison. The electrical device includes a second verification circuit including a first input terminal for the first voltage and a second input terminal for the second voltage, and configured to compare the first and second voltages and to generate a second output signal based on the comparison. Furthermore, the electrical device includes a combination circuit configured to generate a third output signal if the first output signal or the second output signal is indicative of the first voltage or the second voltage being outside a tolerance range.Type: GrantFiled: January 22, 2018Date of Patent: June 1, 2021Inventors: Mario Motz, Umberto Aracri, Alessandro Michelutti

Patent number: 10571296Abstract: A circuit for obtaining information on a physical quantity according to an embodiment includes a sensor arrangement sensitive to the physical quantity, at least one further sensor element sensitive to the physical quantity and a supply circuit configured to provide the sensor arrangement with a supply signal comprising a supply voltage controlled by the supply circuit in a closed-loop configuration. The supply circuit is further configured to provide the at least one further sensor element with a further supply signal comprising a further supply current such that a magnitude of the further supply current fulfills a predetermined relationship with a magnitude of a supply current of the supply signal. As a consequence, it may be possible to improve a trade-off between an improved compensation of variations, simplifying an implementation, simplifying the manufacturing, simplifying the sensing and providing stable sensing conditions.Type: GrantFiled: October 11, 2016Date of Patent: February 25, 2020Assignee: Infineon Technologies AGInventors: Alessandro Michelutti, Bernhard Schaffer, Wolfgang Horn, Simon Hainz
