Embodiment Construction
[0024] The present invention will be further described below in conjunction with the accompanying drawings.
[0025] Such as Figure 1-3 As shown, a method for optimizing the static characteristics of magnetoresistance based on the sensing direction, specifically includes the following steps:
[0026] Step 1. Set the easy-axis bias field and the hard-axis bias field to constant values, set the value of the sensing direction, and obtain the relationship between the reluctance change rate and the normalized magnetic field on the two-dimensional coordinates according to the output function of the sensor Sensing curve;
[0027] Step 2. Select the maximum value h of a specific magnetic field measurement range FM , pass the sensing curve through the objective function optimization, where f(h F ) is the output function of the bridge chip, h F is the external magnetic field, h FM is the maximum value of the magnetic field measurement range, k and b are the sensitivity and bias ...
