Abstract

An essential parameter in the setting up of the performance of the measurement systems that uses Hall microsensors is the detection limit of such devices. This paperwork presents the structure, the operating conditions, and the main characteristic for the Hall semiconductor plates and for double-collector magnetotransistors. By using numerical simulation, the values of signal-to-noise ratio and the detection limit for the two analyzed devices are compared and it is also emphasized the way in which choosing the geometry and the material features allows getting high-performance sensors.
