Paper Title:
Research of Linear Differential Hall Sensor Modeling and Output Characteristics Experiment
  Abstract

The purpose of this paper is to model and study linear differential Hall sensor. A component for linear differential Hall sensor model was constructed, then a number of experiments were performed to check its output characteristics and temperature characteristics.Two Hall-components formed a linear differential Hall model,which had two independent outputs outputing differential voltage. The results show that the model significantly reduces quiescent output voltage, the signal amplitude increased 99.5%, sensitivity ≥ 40mV/mT, linearity error ≤ 0.5%, zero drift coefficient ≤0.023mV/°C.It is concluded that outputing differential voltage can prohibit common-mode interference and zero shift.The model will has self temperature compensation and nonlinear correctiion.In the future ,this model will practicaly in the current sensor.
