Abstract: A power module is provided that is configured to supply power to a load. The power module includes a current generator, a current rail, and a magnetic sensor. The current generator is configured to generate a current. The current rail is configured to receive the current and output the current from the power module. The current rail includes a first opening formed therethrough, and the current, while flowing along the current rail in an output direction, produces a magnetic field. The magnetic sensor is disposed in the first opening of the current rail, and is configured to generate a differential sensor signal based on the magnetic field impinging thereon. The current generator is further configured to regulate the current based on the differential sensor signal.
