Techniques based on spin resonance effects are amongst the most powerful analytical methods in both modern chemistry and medicine. Recent years have seen a trend toward scaled-down detection coils, exploiting the fact that a reduction of the detector size ...
Integrated circuit Hall sensor system comprising a plurality of elementary blocks (EB), each elementary block including a Hall cell (4), a differential pair (8) of an input stage of a Differential Difference Amplifier (DDA), and terminals (12a, 12b), where ...
