DEVICE FOR MEASURING CURRENT USING SENSOR CHIP AND SENSOR

PROBLEM TO BE SOLVED: To improve the dependency on the temperature gradient of a sensor chip by arranging the corresponding magnetoresistive layer strips in one region mirror symmetrically to each other with respect to a barber pole structure. SOLUTION: Two magnetoresistors are arranged in two regions I, II through a constant interval (a) starting from one central axis 15. The resistors comprise common and discrete strips 1'-4' arranged in parallel while having barber pole structure mirror symmetric for all resistors. Consequently, a bridge is excited with only one applying field gradient. Two magnetoresistors are provided for same branch of bridge and collected spatially in the regions I, II.
