MOSFET RF Characterization Using Bulk and SOI CMOS Technologies

摘要

MOSFET radio-frequency characterization and modeling is studied, both with SOI CMOS and bulk CMOS technologies. The network analyzer measurement uncertainties are studied, as is their effect on the small signal parameter extraction of MOS devices. These results can be used as guidelines for designing MOS RF characterization layouts with as small an AC extraction error as possible. The results can also be used in RF model extraction as criteria for required optimization accuracy. Modifications to the digital CMOS model equivalent circuit are studied to achieve better RF behavior for the MOS model. The benefit of absorbing the drain and source parasitic series resistances into the current description is evaluated.
