Abstract: 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 spinning - current principle is applied. In this paper 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” and senses all 3 filed dimensions. The flux-density of BZ is proportional to the DC component of the output signal, whereas the BX and BY components are proportional to the first harmonic of the output signal. Furthermore we calculate the function which governs the changes in the electric field inside the new Hall effect sensor in presence of magnetic field. This function help us to control in MatLab environment the equipotential lines and to monitor the changes in biasing conditions. About the new sensor, the combination of his pioneering form and the elaborate sequence of using the dynamic spinning current technique, cou ld be lead to satisfactory results of produced Hall voltage with small noise in a presence of external magnetic field.
