Abstract
The effect of S parameter measurement errors resulting from vector network analyzer uncertainties on RF MOSFET parameter extraction are analyzed. The uncertainty effects on the MOSFET small signal equivalent circuit are studied. The total differential error on input and output resistances and capacitances and also on the transconductance and feedback capacitance were calculated. The results suggest that the input resistance extraction is very inaccurate. Transconductance and feedback capacitance can be extracted with less than 4% error at low frequencies below 2 - 3 GHz. Output capacitance is challenging because it can easily be 50% erroneous whereas the output resistance error is less than 20% for typical MOSFET output real part range of 3 Ω to 1 kΩ.
