Abstract :
A new silicon integrated 2D Hall sensor for high-accuracy magnetic-field in-plane vector measurements fabricated through a CMOS technology, has been suggested and tested. Its unique advantage is minimal design complexity: only four external connections, lack of cross-sensitivity between the channels and very high resolution. In addition, a simple, but highly effective circuitry fully compensates for the offsets and the nonlinear magnetoresistance of the two outputs
