The invention provides a Hall sensor element having a substrate, which has a main surface, having an electrically conductive active region, which extends from the main surface into the substrate, and having a first electrically conductive, buried layer in the substrate, which contacts the active region at a first lower contact surface. From another standpoint, the invention provides a method for measuring a magnetic field with the aid of such a Hall sensor element, in which an electrical measuring current is conducted through the active region between a first upper contact electrode at the main surface and the first lower contact surface. A Hall voltage is picked up in the active region along a path running inclined with respect to a connecting line between the first lower contact surface and the first upper contact electrode. Alternatively, a measuring current is conducted through the active region over such a path, and a Hall voltage is picked up between the first upper contact electrode and the first lower contact surface.

Hall sensor element and method for measuring a magnetic field

A current sensor for measuring a current in a conductor includes two magnetic field sensors located adjacent to the conductor. The magnetic field sensors are at least two-dimensional magnetic field sensors having two measuring directions, thereby facilitating compensation for an inhomogeneous interference field.

Current sensor, current measuring module and method for measuring current

A circuit for converting the capacitive signal change of a differential capacitor into digital signals, the circuit including a sigma delta modulator. The differential capacitor is a component of the signal feed structure and the reference feedback structure of the sigma delta modulator.
