Abstract :
We describe: (i) an accurate way to enforce charge conservation with minimal disruption of the model extraction process; (ii) the correct way to smooth drain conductance and transconductance data for deriving large-signal drain current; and (iii) a priori identification of ill-conditioned parameters in small-signal models which are intrinsically difficult to measure
