Characteristics of 2D magnetic field sensor based on magnetic sensitivity diodes
Source abstract
Abstract
A two-dimensional (2D) magnetic field sensor is proposed in this paper. It contains two Wheatstone bridges composed of four magnetic sensitivity diodes(MSDs)with similar characteristics and four loading resistances. In order to realize the axial symmetric distribution of four MSDs, two MSDs with opposite magnetic sensitive directions were located along the x and −x axes, and two with opposite magnetic sensitive directions were located along the y and −y axes. The experimental results indicate that when VDD = 5.0 V, the magnetic sensitivities of the 2D magnetic sensor can reach SxB = 544 mV/T and SyB = 498 mV/T in the x and y directions, respectively. Consequently, it is possible to measure the two-dimensional magnetic field.
