## Low Noise CMOS Micro-Fluxgate Magnetometer

We present a new two-axis fluxgate magnetometer fully integrated in CMOS technology. The magnetometer exhibits excellent sensitivity of 2700 V/T and the magnetic equivalent noise spectral density of 6nT/√Hz at 1 Hz. The total power consumption is as low as 35 m W from the single 5 V power supply. The low noise characteristic is obtained using the combination of good magnetic . material properties and electronic post-modulation technique to reduce the noise coming from CMOS electronic part.
