FDSOI devices are prominently used in low power circuits and high frequency domains due to their superior RF and analog performance, thanks to back-bias capability and relatively ease of transistor design over FinFETs and planar bulk transistors. BSIM-IMG is the industry standard compact model for simulating FDSOI devices. In this work, we will discuss recent enhancements made in the BSIM-IMG model for accurate modeling of the FDSOI transistors. The back gate inversion is more physically modeled in the latest BSIM-IMG model. We will present a new 1/f noise model, which is validated with the experimental data. Improved output conductance, mobility and gate current models are also discussed. All the enhancements are done in such a way that benchmark RF figure of merit are met. © 2020 IEEE.
