    Abstract: A sensor device contains a first magnetic field sensor chip having a first sensor element. The first magnetic field sensor chip is configured to detect a component of a magnetic field at the location of the first sensor element. The sensor device contains a second magnetic field sensor chip having a second sensor element. The second magnetic field sensor chip is configured to detect a component of a magnetic field at the location of the second sensor element. The sensor device contains a current conductor configured to carry a measurement current that induces a magnetic field at the locations of the sensor elements. The magnetic field sensor chips and the current conductor are arranged relative to one another in such a way that an influence of a homogeneous magnetic stray field on the first components is compensated for upon difference formation or summation applied to the first components.

    Abstract: According to an exemplary embodiment, a semiconductor component includes a chip carrier, a semiconductor chip mounted on the chip carrier, and a chip package made of potting compound. The potting compound only partially surrounds the semiconductor chip, such that at least part of an upper side of the semiconductor chip is not covered by the potting compound. The semiconductor component further includes a clip that is mechanically connected to the upper side of the semiconductor chip.

    Abstract: An apparatus for in-situ calibration of a photoacoustic sensor is provided. The apparatus includes a calibration unit that includes at least one processor configured to calculate calibration information. A light emitter of the photoacoustic sensor is configured to emit an electromagnetic spectrum and the photoacoustic sensor is configured to provide at least two measurement signals based on at least two electromagnetic spectra. The calibration unit is configured to compare the at least two measurement signals to obtain the calibration information and apply the calibration information to the photoacoustic sensor to perform the in-situ calibration.

    Abstract: A photoacoustic sensor includes a first layer with an optical MEMS emitter; a second layer stacked over the first layer with a MEMS pressure pick-up and an optically transparent window, wherein the MEMS pressure pick-up and the optically transparent window are offset laterally with respect to one another; and a third layer stacked over the second layer with a cavity for a reference gas. The optical MEMS emitter transmits optical radiation along an optical path, wherein the optical path runs through the optically transparent window and the cavity for the reference gas, and wherein the MEMS pressure pick-up is outside the course of the optical path.
