Abstract
We present the design and experimental characterization of a magnetic field sensor. This sensor is based on an array of Hall resistors and uses lateral BJTs as active elements to read the effect of the magnetic field on it. Its output is in current mode, instead of the more frequent voltage mode. Results show that a raw sensibility of 5mA/T can be achieved, with no measurable hysteresis.
