Non-linear FinFET Modeling: Lookup Table and Empirical Approaches

Artikel i vetenskaplig tidskrift, 2008

The non-linear microwave modeling of advanced transistors is becoming more and more essential to the design and fabrication processes. Consequently, this study is focused on the equivalent circuit based non-linear microwave modeling of FinFET. An accurate multi-bias small signal equivalent circuit is extracted and subsequently used for analytically constructing a non-linear full blown lookup table model. Furthermore, an alternative model implementation, which is based on empirical expressions, is investigated. The validity of both non-linear modeling approaches is confirmed by the good agreement between model simulations and large signal measurements.
