Patent ID: 8547087

Claim:
A magnetic field sensor assembly configured to measure an angular direction (φ) of a sensed magnetic field (H appl ) relative to the assembly, the sensor assembly comprising: a sensor of a first type configured to sense an orientation of the sensed magnetic field; a sensor of a second type, comprising at least one Hall effect sensor, that is configured to measure the orientation and a direction of the sensed magnetic field; and processing circuitry connected to each of the magnetic field sensors, the processing circuitry being configured to process output signals from the sensor of the first type to determine an uncorrected sensed magnetic field angle and to apply an offset angle to the uncorrected magnetic field angle dependent on a logical combination of signs of output signals from the sensors of the first and second types, wherein the sensor of the first type and the sensor of the second type are formed on a single die, and wherein the at least one Hall sensor is located between first and second sensor bridge.
