Abstract
A magnetoresistive sensor with harmonically broadened linear range comprises a substrate () and a multiple push-pull magnetoresistive sensing bridge arms. The push arms () of the sensing bridge comprise N types of push magnetoresistive sensing units (). The pull arms () comprise N types of pull magnetoresistive sensing units. Key characteristic parameters of each magnetoresistive sensing unit comprise R, MR, H, ±αand a. The Key characteristic parameters of the push magnetoresistive sensing units () and corresponding pull magnetoresistive sensing units are different from the key characteristic parameters of standard magnetoresistive sensing unit of a standard push-pull linear magnetoresistive sensor. There is at least one set of key characteristic parameters [(R, MR, H, ±α), a]. Linear parts and nonlinear harmonic parts of R-H characteristic parameters that characterize the push magnetoresistive sensing units and the pull magnetoresistive sensing units are superimposed, so that the linear range of the multiple push-push magnetoresistive sensing bridge is greater than the linear range of the standard push-pull linear magnetoresistive sensor.
