Abstract
Sensing systems and methods are provided for compensating for offset and gain changes. A sensing system includes a magnetic element, a current sensing arrangement to provide a current measurement signal influenced by a flux induced in the magnetic element, an oscillator arrangement to provide a reference oscillating current signal configured to induce an oscillating flux in the magnetic element, and a compensation arrangement coupled the current sensing arrangement to adjust the current measurement signal to compensate for gain changes in the measurement signal output and provide a compensated current measurement based at least in part on the adjusted measurement signal and the reference oscillating current signal. The oscillating flux influences the current measurement signal output by the current sensing arrangement.
