Modeling of Metal-Semiconductor Field-Effect-Transistor on H- terminated polycrystalline diamond

On the bases of the RF characteristics and measured small-signal parameters, an equivalent circuit model is formulated and characterized for Metal-Semiconductor Field Effect Transistors based on H-terminated polycrystalline diamond. Starting from on-wafer measurements, a bias dependent transistor behavior representation has been fully determinated. Such a equivalent circuit model is a first important step in order to realize an RF IC based on diamond.
