The paper presents numerical model and validation of new methodology of offset voltage minimization in the Hall-effect sensors. Model of the Hall-effect sensor with multiple electric pins was developed. Mathematical equations used for calculation of electric potential difference were formulated. Simulations were carried out using finite elements method in ELMER FEM software. Performed investigation of actual parameters of newly designed Hall-effect sensor confirms effectiveness of the described method.
