Abstract:
A new approach to design high performance microsystems is proposed. It is based on the association between a low-cost sensor array and a multidimensional signal processing technique: the so-called 'blind source separation'. In order to illustrate the effectiveness of the method, we applied the source separation processing for a Hall-type silicon sensor array in order to cancel the temperature cross-sensitivity and spurious magnetic field sources crosstalk. A microsystem prototype including the Hall sensor array, conditionning electronics and a DSP running source separation algorithm is currently designed.
