P5.4 - Novel Dynamic Technique Reducing the Offset Voltage in a Hall Effect Sensor
2011
Silicon Hall plates show an offset of a few millitesla. A large portion of this offset is caused by mechanical stress in the device. The offset can be reduced when the spinningcurrent principle is applied. In this work we present a model and numerical analysis of a new Hall effect sensor which using a novel offset reduction method. We call it "Wheel Hall Senor".The device exploits the signals attributed to Hall voltage, Hall current and geometric MR effect. As a result the Device is equivalent
