Single-chip push-pull bridge type magnetic field sensor. The sensor includes a substrate (1), a bonding pad (6-9), comprising a magnetoresistive sensing element (10, 11), the magnetic flux concentrator and (12, 13), the magnetoresistive sensing element (10, 11 ), the direction of the adjacent aligned with the gaps (14, 15) of the flux concentrator (12, 13), and the pinning layer of the magnetoresistive sensing element (10, 11) are identical. Flux concentrator (12, 13) is divided into a push-arm and pull arms type, inner included angle between one type and the X-axis forward direction is positive, and the other types and the X-axis before internal included angle between the direction is negative. The operating principle of the sensor, the magnetic field along the X-axis direction in the gap (14, 15) of the flux concentrator (12, 13) are opposite, are those called. The sensor has a low cost small size, is simple to manufacture, excellent in linearity with high sensitivity, strong detection signal, the operation the dynamic range is wide, has a advantage such.
