Abstract
A current sensor including: a sensing unit including one or more sensing elements, the sensing unit being arranged to generate, at least in part, an internal signal, the internal signal being generated in response to a magnetic field, the magnetic field being produced, at least in part, by an electrical current that is sensed with the sensing unit; a first signal processing path coupled to the sensing unit, the first signal processing path including a first compensation unit for adjusting the internal signal, the first signal processing path being configured to generate a first signal based on the internal signal; a second signal processing path coupled to the sensing unit, the second signal processing path including a second compensation unit for adjusting the internal signal, the second path having a different sensitivity than the first path.
