Hall Effect Sensors: Principles and Applications

This lecture covers the principles and applications of Hall effect sensors, focusing on the zero current in y and z directions, the sensitivity to current and voltage, the geometric factors affecting the hall voltage, and the noise and resolution considerations. It also discusses the importance of high mobility materials, weak doping, and the necessary characteristics for obtaining good resolution in Hall effect sensors. Additionally, it explores the manufacturing of Hall sensors in silicon, typical applications such as in sensors for angular position and speed, and the use of magnetic materials with great resistance and mobility.
