Abstract An analytical MOSFET model is presented that accounts for energy quantization in inversion charge and depletion in the poly gate. The model consistently describes effects on charges, transcapacitances, drain current and transconductances in all regions of operation, depending on five physical device parameters and bias conditions. Comparison to experimental data is provided and parameter extraction briefly discussed. The model offers manageable equations providing insight into the physical phenomena, thereby supporting analog circuit design practice as well as efficient circuit simulation
