Claim Text:
1. A magnetic-field sensor, comprising: a substrate having a first surface and a second surface; an insulating layer on the first surface; a first magnetoresistor extending in the insulating layer and having a main axis of magnetization and a secondary axis of magnetization; a second magnetoresistor extending in the insulating layer and having a main axis of magnetization and a secondary axis of magnetization, the main axis of magnetization of the second magnetoresistor extending in a direction transverse to the main axis of magnetization of the first magnetoresistor and the secondary axis of magnetization of the second magnetoresistor extending in a direction transverse to the secondary axis of magnetization of the first magnetoresistor; 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; and 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, wherein the first and second magnetoresistors extend in the insulating layer at respective first and second distances from the first surface, the first and second distances being different from one another.
