Patent ID: 8884616

Claim:
An angle sensor for measuring an external magnetic field with 360 degrees of uniqueness comprising: a tunneling magnetoresistive (TMR) stack having a tunneling barrier layer, a layer exhibiting an anisotropic magnetoresistive (AMR) effect and a first electrode on a first side of the tunneling barrier layer, a second electrode on a second side of the tunneling barrier layer, and first and second contact sets on the first side of the tunneling barrier, wherein the first electrode exhibits an AMR effect; wherein the TMR stack has a first sensor configuration to sense a first condition in the TMR stack when the first contact set is used and a second sensor configuration to sense a second condition in the TMR stack when the second contact set is used, contacts of the first contact set being spaced apart from one another by a first distance and contacts of the second contact set being spaced apart from one another by a second distance different from the first distance.
