Inhalt:
An essential parameter in the setting up of the performance of the measurement systems that uses Hall microsensors is the magnetic offset of such devices. This paperwork presents the structure, the operating conditions, and the main characteristic for double drain magnetotransistors and for vertical bipolar magnetotransistor. By using numerical simulation, the values of the offset-equivalent magnetic induction for two analysed devices are compared and it is also emphasised the way in which choosing the geometry and the material features allows getting high-performance sensors.
