Abstract
A magnetoresistive angular sensor ( ) is provided which determines a magnetic field direction. A high angular accuracy over a wide range of magnetic field strengths is obtained. The magnetoresistive angular sensor comprises a main sensing element ( ) which is electrically connected to a first correction sensing element ( ) with a first reference magnetization axis ( ) and a second correction sensing element ( ) with a second reference magnetization axis ( ), the first ( ) and the second ( ) reference magnetization axes making correction angles &THgr; between 5° and 85° of opposite sign with the main reference axis ( ).
