Integrated Fluxgate Magnetometer for Use in Isolated Current Sensing

This paper presents two integrated magnetic sensor ICs for isolated current measurement that have a fluxgate magnetometer co-integrated along with circuitry on a die. The integrated fluxgate has a sensitivity of 250 V/T and a 500 ksps readout circuit and requires only 5.4 mW for fluxgate excitation,...
