Abstract:
A magnetic sensor including sensor bridge circuits, each including a pair of magnetic field detectors and a pair of fixed resistors. The magnetic field detectors in each bridge circuit are located on the same inclined surface, while the fixed resistors are each located on a different inclined surface. The inclined surface configuration reduces the number of fabrication steps necessary to fabricate the magnetic sensor.
