6. Detailed Description
As described on the block diagram (Figure 1 and Figure 2), the magnetic flux density parallel to the IC
surface (i.e. B//) is sensed through the Tria⊗is™ sensor front-end. This front-end consists into two
orthogonal pairs (for each of the two directions parallel with the IC surface i.e. X and Y) of conventional
planar Hall plates (blue area on Figure 4) and an Integrated Magneto-Concentrator (IMC
® yellow disk on
Figure 4).
