Abstract

The noise-signal at the output of a Hall magnetic sensor can be interpreted as a result of an equivalent magnetic induction, acting on a noiseless Hall device. In this paperwork based on the adequate models it is analysed the operating conditions, and are established the noise main characteristic for three magnetic microsensor structures, realized in the bipolar and the MOS integrated circuits technology. By using the numerical simulation the values of the signal-to-noise ratio and the noise-equivalent magnetic induction spectral density for different structure devices are compared and it is also emphasized the way in which choosing the geometry and the material features allows getting high-performance sensors. (properties influence on the device performances.)
