The recent progress in SOI technology necessitates an accurate thermal noise model for wide-band SOI analog 1C design. In this paper a physical-based thermal noise model is proposed for floating-body SOI MOSFET operated in strong inversion regime and verified by the experimental data. In the model, both the lattice temperature (unique to SOI due to the buried oxide) and the carrier temperature (significant for short-channel device in saturation region) are considered. The model agrees well with the experimental data.
