Accurate Small-Signal Modeling of FD-SOI MOSFETs

A new small-signal model for fully depleted silicon-on-insulator (FD-SOI) MOSFETs operating at RF frequencies is presented. The model accounts for the non-quasi-static effect by determining model parameters using a curve fitting procedure to reproduce the frequency response of FD-SOI MOSFETs. The accuracy of the model is validated by comparison of S parameters with measured results in the range from 0.2 GHz to 20 GHz.
