Abstract
A two-dimensional analog angular magnetic sensor device for measuring an orientation of an external magnetic field, comprising at least a magnetic sensor, comprising a plurality of tunnel magnetoresistance (TMR) elements arranged in a full-bridge configuration and configured to provide a sine output voltage: V=A·sin θ·V, or configured to provide a cosine output voltage V=A·cos θ·V, wherein A is parameter depending on the TMR ratio of the TMR element and Vis a bias voltage inputted to the magnetic sensor. The magnetic sensor device further comprises an analog circuit configured to generates a circuit output voltage and electrically connected to the magnetic sensor such as that the magnetic sensor device generates a device output voltage that follows one of: a tangent output voltage V:V=K·V·V=K·V·tan θ, where K is a constant; or a cotangent output voltage (V):
