Methodology of Reduction of the Offset Voltage in Hall-Effect Sensors

Maciej Kachniarz , Oleg Petruk , Roman Szewczyk


The paper presents new, original methodology of reduction of the offset voltage in Hall-effect sensors. The outline of innovative Hall-effect sensor with five electrical pins for each electrode is presented. Such a construction creates a possibility to use different combinations of pins in order to find minimum value of the offset voltage. The procedure of searching for the best combination of pins connected for minimization of the value of offset voltage is also presented. For practical implementation of the methodology, special experimental system was developed, utilizing system of relays controlled by Data Acquisition Card to set different combinations of pins and search for the minimum value of the offset voltage. Obtained results indicate that there is a possibility to reduce value of the offset voltage even up to one hundred times.
