Abstract
A magnetic-field sensor includes: a chip including a substrate having a first surface and an insulating layer covering the first surface; first and second magnetoresistors each extending into the insulating layer and having a main axis of magnetization and a secondary axis of magnetization; a first magnetic-field generator configured to generate a first magnetic field having field lines along the main axis of magnetization of the first magnetoresistor; a second magnetic-field generator configured to generate a second magnetic field having field lines along the main axis of magnetization of the second magnetoresistor. The main axes of magnetization extending transversely to each other and the secondary axes of magnetization extending transversely to each other. The first and second magnetoresistors extend into the insulating layer at a first distance and a second distance, respectively, that differ from one another, from the first surface.
