US Patent 11467233 Linear bridges having nonlinear elements

In one aspect, a bridge includes a first magnetoresistance element having a first reference angle, a second magnetoresistance element in series with the first magnetoresistance element and having a second reference angle, a third magnetoresistance element in parallel with the first magnetoresistance element and having the first reference angle and a fourth magnetoresistance element in series with the third magnetoresistance element and having the second reference angle. An output of the bridge has a linear response over a range of horizontal magnetic field intensity values not centered about a zero value and a reference angle indicates an angle the magnetoresistance element is most sensitive to changes in a magnetic field.
