Research of Linear Differential Hall Sensor Modeling and Output Characteristics
In this paper, a novel components model of linear differential Hall sensor is proposed and its output characteristics and temperature characteristics is investigated in detail. 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/℃. Differential output model can suppress common mode interference and zero drift, the model has a temperature self-compensation and non-linear correction function, which is suitable for Hall current sensor design.
