The main noise characteristics for MOS magnetic sensors

The paper presents the results of research work regarding the analysis and optimization of magnetic microsensors realized in MOS integrated circuits technology. On the basis of adequate models these have been established the noise main characteristics for MOS-Hall plates and for double-drain MOSFET magnetotransistors. By using the numerical simulation the values of the signal-to-noise ratio and the detection limits for the two analysed structured are compared and it is also emphasized the way in which choosing the geometry and the material features allows getting high-performance sensors.
