Abstract :
A 2D model dedicated to MAGFET-type sensors is presented. It is applied to a new device design, the CHOPFET and dedicated to accelerating the conception of CHOPFET-based instrumentation systems. FEM Simulation show significant dependence of the geometric parameters on the device´s characteristics. The model allows optimization to achieve maximum sensitivity. A compact model for CAD design is also proposed and yields satisfactory simulation results.
