State of art of 28 nm RF MOSFET is studied using sentaurus process and device tools. DC characteristics, such as C-V, Rs, Rd and I-V curves are calibrated by adjustment of physics model. The relationship between saturation velocity (vsat), energy relaxation time (τ) and high field mobility are studied. What’s more, RF noise simulated with different vsat and τ is presented. The lower these two parameters are, the lower noise parameter we get
