Abstract
A magnetic sensor circuit provides current sources that create a feedback loop for an amplifier of one magnetically sensitive component in order to maintain the sensor output and the corresponding amplifier input at a first preselected magnitude which can be generally equal to zero. The other current source maintains a generally identical current as a reference against which the output of another magnetically sensitive component is compared. The magnetically sensitive components can be Hall effect elements, indium antimonide sensors or magnetoresistive elements. The output of the circuit is representative of the difference between the magnetic field intensities imposed on the first and second magnetically sensitive components.
