Abstract

An uncertainty estimation and ensitivity analysis is performed on multi-step de-embedding for SiGe HBT small-signal modeling. The uncertainty estimation in combination with uncertainty model for deviation in measured S-parameters, quantifies the possible error value in de-embedded two-port parameters (Y and Z-parameters). The analysis is applied to a 0.35µm 60GHz fT SiGe HBT in frequency range 45MHz to 26GHz.
