Abstract: In some examples, a device includes a first conductive region and a second conductive region that is galvanically isolated from the first conductive region. The device further includes one or more conductors, wherein each conductor of the one or more conductors is electrically connected to circuitry in the first conductive region. The device also includes a giant magnetoresistive (GMR) sensor electrically connected to circuitry in the second conductive region and magnetically coupled to the one or more conductors, wherein the GMR sensor is positioned at least partially lateral relative to the one or more conductors.
