| 摘要 |
The present invention relates to a magnetic field sensing device (50) comprising several functionally different layers (38, 60, 70), wherein a Wheatstone bridge layer (70) comprises at least two resistors (20) of a Wheatstone bridge (18), each resistor (20) comprises at least one magnetic field sensing element (10) in the form of a resistor subelement (22), and a flip conductor layer (38) comprising at least one flip conductor (30) for flipping the internal magnetization state of each magnetic field sensing element (10). The flip conductor (30) comprises a plurality of conductor stripes (32) being arranged on at least two different flip conductor sublayers (38-1, 38-2) of said flip conductor layer (38) and being electrically coupled with each other through vias. The multilayer arrangement of said flip conductor (30) provides a compact design of said magnetic field sensing device (50), such that a decreased power consumption, decreased inductance and improved sensitivity of the magnetic field sensing device can be achieved. |
