Integrated AMR magnetoresistor with large scale

An integrated magnetoresistive sensor of an anisotropic magnetoresistance (AMR) type, comprising:

• a plurality of magnetoresistive units positioned adjacent each other, wherein each magnetoresistive unit comprises:
• a magnetoresistive strip having a length in a first direction and a width in a second direction perpendicular to the first direction;
• a set/reset coil having a stretch transversely extending to the first direction;
• and
• a shielding region of ferromagnetic material having a width in the second direction greater than the width of the magnetoresistive strip;
• wherein the shielding region of a first one of the plurality of magnetoresistive units has a first width and the shielding region of a first one of the plurality of magnetoresistive units has a second width different from the first width.

An integrated magnetoresistive sensor of an anisotropic magnetoresistance (AMR) type, comprising:

• a magnetoresistive strip of an elongated shape having a first length in an easy-axis direction and a first width in a hard-axis direction perpendicular to the easy-axis direction;
• a set/reset coil carrying current in the hard-axis direction;
• and
• a shielding region of ferromagnetic material having a second length in the easy-axis direction and a second width in the hard-axis direction;
• wherein the second width is greater than the first width.
