Magnetic field sensor circuit in package with means to add a signal from a coil

A magnetic field sensor system comprising:

• a magnetic field source configured to generate a first magnetic field, a second magnetic field, and an electric field;
• a first magnetic sensor configured to measure the first magnetic field in a first frequency range and output a first sensor signal based on the measured first magnetic field;
• a second magnetic sensor configured to measure the second magnetic field in a second frequency range and output a second sensor signal based on the measured second magnetic field;
• a sensor circuit comprising a first input terminal and a second input terminal, the sensor circuit being electrically coupled to the first magnetic sensor and the first input terminal and the second input terminal being electrically coupled to the second magnetic sensor, the sensor circuit configured to receive the first sensor signal and the second sensor signal, and output a combined sensor signal derived from the first sensor signal and the second sensor signal;
• a substrate comprising a first main surface and a second main surface arranged opposite to the first main surface;
• and
• an electric shield disposed in the substrate, between the second magnetic sensor and the magnetic field source, the electric shield configured to shield at least the second magnetic sensor from the electric field generated by the magnetic field source,
• wherein the second magnetic sensor is a differential inductance coil having a first winding and a second winding coupled together in a subtracting configuration, the first winding being configured to generate a first component of the second sensor signal and provide the first component to the first input terminal of the sensor circuit, the second winding being configured to generate a second component of the second sensor signal and provide the second component to the second input terminal of the sensor circuit.
