Abstract

A bridge sensor (100) comprising at least one dummy resistor structure (110), at least one magnetic sensor structure (120), a first and a second regulator (130, 140), the dummy resistor structure and the sensor structure being bridge structures. The first regulator (130) is adapted to apply a predefined bias voltage between bias contacts of the at least one dummy resistor structure (110) and a related current at one of bias contacts of the at least one sensor structure (120). The second regulator (140) is adapted to regulate a dummy common mode voltage of the at least one dummy resistor structure (110) such that the dummy common mode voltage of the at least one dummy resistor structure (110) is the same as the common mode voltage of the at least one sensor structure (120).
