In this paper we present a complete low-voltage, low-power and high linearity CMOS interface circuit for fluxgate magnetic sensors for current measurement applications. The integrated circuit provides the correct excitation signal to the fluxgate sensors and reads-out the sensor signals from the sensing coils. The proposed circuit allows us to deal with sensors featuring different values of the excitation...
In this paper we present an acquisition system to measure the Earth magnetic field (whose full-scale value is of the order of 60 muT), consisting of a microcontrolled management subsystem, a CMOS integrated interface circuit and a 2D integrated micro-flux gate magnetic sensor. The couple of orthogonal axis of the sensor makes the system suitable for realizing an electronic compass device. The complete...
