Both components of the applied flux density B
components (respectively B
are induced through the IMC and can be measured by both respective pairs of conventional planar Hall
plates as those are sensitive to the flux density applied orthogonally to them and the IC surface.
While a magnet (diametrically magnetized) rotates above the IC as described on Figure 3, the sensing
stage provides two differential signals in quadrature (sine and cosine − Figure 5 and Figure 6)
