Patent ID: 11199424

Abstract:
In one aspect, a magnetic field angle sensor includes a bridge structure that include a sine bridge configured to generate a sinusoidal signal indicative of a magnetic field along a first axis and a cosine bridge configured to generate a cosinusoidal signal indicative of the magnetic field along a second axis that is orthogonal with respect to the first axis. One of the sine bridge or the cosine bridge includes a first set of at least two magnetoresistance elements, a second set of at least one magnetoresistance element, a third set of at least one magnetoresistance element and a fourth set of at least one magnetoresistance element. An average reference direction of the first set of at least two magnetoresistance elements is equal to an average reference direction of the third set of at least one magnetoresistance element. An average reference direction of the second set of at least one magnetoresistance element is equal to an average direction angle of the fourth set of at least one magnetoresistance element.
