Abstract: Embodiments relate to magnetic field angle sensors, such as on-axis magnetic field angle sensors. In an embodiment, a magnetic field angle sensor comprises a magnet having an axis of rotation, and a substrate arranged in-line with the axis of rotation. A plurality, such as at least four, of magnetic field sensor elements are arranged on a surface of the substrate, spaced apart from one another in regular increments on a closed curve in an embodiment, and are sensitive to a component of a magnetic field induced by the magnet that is parallel to the surface of the substrate on which the sensor elements are arranged. Circuitry of or coupled to the sensor elements then can estimate an angular position of the magnet, such as based on the magnetic field components sensed by the sensor elements as well as positions along the closed curve where the magnetic field component vanishes in an embodiment.

Abstract: The innovative concept described herein relates to a sensor chip having at least two magnetic field sensors that are arranged adjacently to one another on the sensor chip and measure perpendicularly to the chip plane, wherein at least one of the magnetic field sensors has a planar coil arranged on it that is configured to generate a magnetic field directed perpendicularly to the chip plane. A controller is able to operate the magnetic field sensors in a calibration mode, in which the planar coil generates the magnetic field. For the purpose of calibrating the magnetic field sensors, a differential measurement may be taken that involves the response signal from one magnetic field sensor being subtracted from the response signal from the other magnetic field sensor.

Abstract: The described techniques are directed to inductive torque sensors that implement independent target coil and pickup coil systems. By utilizing the various principles of inductive angle sensors, and as a result of the specific physical arrangement of target coils, the inductive torque sensor may independently obtain a rotational position (i.e., mechanical angle) of the rotatable input shaft via one pickup coil system, and a rotational position (i.e., mechanical angle) of the rotatable output shaft via another pickup coil system. Combiner circuitry is also provided to calculate the torsion angle using the signals induced in each of two separate pickup coil systems. By using different k-fold symmetry periodicities in the target coils with respect to the coil configurations, the inductive torque sensor advantageously reduces or eliminates mutual coupling between the different target coil systems and provide robustness to stray or external electromagnetic fields.

Abstract: The described techniques facilitate the use of a magnetic field sensor that implements the same magnetic layer stack for the detection of the x, y, and z components of an external magnetic field. The sensor advantageously is insensitive to orthogonal stray fields and operates with a reduced offset compared to conventional magnetic field sensors. The linear regime implemented by the sensor to facilitate magnetic field detection may also be adjusted per application by tuning the current strength.

Abstract: An inductive angle sensor for determining a rotational position of a rotor relative to a stator includes an exciter coil, at least one pickup coil arrangement having an m-fold symmetry and at least one conductive target having an m-fold symmetry. The exciter coil may excite the conductive target which, in turn, may induce an induced signal in the pickup coil arrangement. A signal analysis device may determine the rotational position of the rotor based on the induced signal. The inductive angle sensor may comprise a second pickup coil arrangement having an n-fold symmetry and a second conductive target having an n-fold symmetry. The exciter coil may excite the second conductive target which, in turn, may induce a second induced signal in the second pickup coil arrangement. The signal analysis device may determine the rotational position of the rotor based on the two induced signals according to a Vernier principle.
