A simple calibration system for magnetic field sensors was designed, and experiments were carried out to calibrate two-dimensional fluxgate sensors and a sensor ring composed of eight fluxgate sensors. Fast Fourier Transforms and trapezoidal numerical integrals were applied to deal with the raw signals. It is found that it is not suitable to apply fast Fourier Transforms only to deal with signals with several peaks close to each other, but trapezoidal numerical integrals should also be used in combination with the FFT method.

This paper reports the two dimensional (2D) magnetic sensor, which is comprised of twoMOSFET Hall devices with similar characteristics. The sensor is based on the MOSFET Hall deviceprinciple and is fabricated on <100> orientation silicon substrate by adopting complementary metaloxide semiconductor (CMOS) technology and packaging technology. The experiment results indicatethat when VDS =5.0 V, the magnetic sensitivities of the 2D magnetic sensor can reach Sx=34.0 mV/Tand Sy=33.6 mV/T in the x and y directions, respectively, it is necessary to realize the measurementof 2D magnetic field.

Micro magnetic field (MMF) sensors developed employing complementary metal oxide semiconductor (CMOS) technology are investigated. The MMF sensors, which are a three-axis sensing type, include a magnetotransistor and four Hall elements. The magnetotransistor is utilized to detect the magnetic field (MF) in the x-axis and y-axis, and four Hall elements are used to sense MF in the z-axis. In addition to emitter, bases and collectors, additional collectors are added to the magnetotransistor. The additional collectors enhance bias current and carrier number, so that the sensor sensitivity is enlarged. The MMF sensor fabrication is easy because it does not require post-CMOS processing. Experiments depict that the MMF sensor sensitivity is 0.69 V/T in the x-axis MF and its sensitivity is 0.55 V/T in the y-axis MF.
