摘要：
An integrated magnetic-field sensor designed to detect an external magnetic field, comprising a first magnetoresistive structure for detecting the external magnetic field, the first magnetoresistive structure including first magnetoresistive means having a main axis of magnetization and a secondary axis of magnetization set orthogonal to one another. The magnetic-field sensor further comprises a magnetic-field generator, including a first portion configured for generating a first magnetic field having field lines in a first field direction, and a second portion, which is coplanar and is connected to the first portion, configured for generating a second magnetic field having field lines in a second field direction, the first magnetoresistive means being configured so that the main axis of magnetization extends parallel to the first field direction, and the secondary axis of magnetization extends parallel to the second field direction.
