    Abstract: 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.

    Abstract: Embodiments relate to a controller operable to transmit digital data messages to a receiver via a communication link having at least a first and a second transmission path, the controller comprising a first signal terminal the first transmission path and a second signal terminal for the second transmission path. The first signal terminal is operable to digitally transmit a first message to the receiver according to a first transmission technique and the second signal terminal is being operable to digitally transmit a second message to the receiver according to a second, different transmission technique.

    Abstract: Embodiments relate to systems and methods for sensor self-diagnostics using multiple signal paths. In an embodiment, the sensors are magnetic field sensors, and the systems and/or methods are configured to meet or exceed relevant safety or other industry standards, such as SIL standards. For example, a monolithic integrated circuit sensor system implemented on a single semiconductor ship can include a first sensor device having a first signal path for a first sensor signal on a semiconductor chip; and a second sensor device having a second signal path for a second sensor signal on the semiconductor chip, the second signal path distinct from the first signal path, wherein a comparison of the first signal path signal and the second signal path signal provides a sensor system self-test.

    Abstract: A sensor may include a clock generator configured to generate a clock. A receiver may be configured to receive signals from a control unit, and a transmitter they be configured to send signals to the control unit. In one implementation, the transmitter is configured to send a synchronization signal based on the clock. A period between a first edge and a second edge of the synchronization signal may be dependent on the clock and both edges are either rising or falling.
