Abstract
A sensor arrangement for detecting an angle of rotation of a rotating body. At least one first sensor and one second sensor are connected to one another in a cascade in such a manner that the sensor signal from the first sensor is converted into a first control current which is applied as a bias current to the second sensor, the two angular dependencies of the first and second sensors being multiplied. This achieves improved interpolation when determining the angle of rotation on the basis of the sensor signals provided by the sensor arrangement.
