Abstract: An apparatus includes a magnetic bridge sensor generating an output in response to a sensed magnetic field. An amplification stage processes the output to produce an amplified output signal. A field-effect transistor with a gate receives the amplified output signal, a source node receives a current source and a drain node is connected to the magnetic sensor. A regulator is connected to the magnetic bridge sensor. A first contact is connected to the source node to produce a voltage signal characterizing the sensed magnetic field. A second contact is connected to the magnetic bridge sensor and the regulator.
