This paper presents small-signal modeling for state-of-the-art radio-frequency (RF) silicon-on-insulator (SOI) metal-oxide-semiconductor field effect transistors (MOSFETs). Especially, we have incorporated the neutral-body effect in our RF SOI model. This effect is significant in both RF extrinsic and intrinsic modeling stages. In addition, we have developed a physically-accurate parameter extraction method based on our analytical expressions. Our modeling results agree well with the measured data and can capture the frequency dependences of both output conductance and capacitance in the GHz frequency region. The anomalous S22 and S21 behaviors as well as the output conductance rising effect observed in our measurements can be predicted and described using the proposed model.
