KMT32B角位傳感器：

    The KMT32B is a magnetIC field sensor based on the anisotropic magnetoresistance effect. The sensor

 contains two parallel supplied Wheatstone bridges, which enclose a sensitive angle of 45 degrees.

    A  rotating  magnetic  field  in  the  surface  parallel  to  the  chip  (x-y  plane)  will  deliver

two independent sinusoidal output signals, one following a cos(2α) and the second following a sin(2α)

function, α being the angle between sensor and field direction (see Figure 1).
