Hall sensors are active devices manufactured from semiconductor materials, their output voltage drifts with temperature change, which limits their application in high-precision magnetic field measurement. A new symmetrical closed loop Hall current sensor is proposed and systematically designed. The output voltage operation circuit is designed based on the sensitivity difference of Hall element, the working principle of symmetrical closed-loop current sensor is analyzed and the closed-loop transfer function is given. The results of circuit simulation and prototype experiment show that the symmetrical closed-loop Hall current sensor has good temperature characteristics, and the temperature coefficient is reduced to 0. 000 8% / ℃ . Compared with other temperature compensation methods, this method is simple and easy to implement, and can realize the complete compensation of temperature drift. Hall components can be selected arbitrarily according to the measurement needs, and are not limited by the driving mode.
