This paper presents a semi-empirical modeling of MOST and passive elements to be used in narrowband
radiofrequency blocks for nanometer technologies. This model is based on a small set of look-up
tables (LUTs) obtained via electrical simulations. The MOST description is valid for all-inversion regions
of MOST and the data is extracted as function of the gm=ID characteristic; for the passive devices the
LUTs include a simplified model of the element and its principal parasitic at the working frequency
f0. These semi-empirical models are validated by designing a set of 2.4-GHz LNAs and 2.4-GHz and
5-GHz VCOs in three different MOST inversion regions
