Abstract

This paper describes the highly sensitive Si Hall magnetic sensing system which can measure the earth magnetic field. Generally, the important parameters in Hall device which degrade the ability of magnetic detection are offset voltage and 1/f noise. The offset voltage and 1/f noise in Hall plates can be reduced by spinning current method. In this paper, we implement the highly sensitive Si Hall magnetic sensing system using spinning current method. As a result, the minimum detectable magnetic field is 0.1G.
