mos transistor modell high frequency
yeah , usually foundries provide two sets of transistor models , the normal model which is used for low frequancy analog blocks and DC bias networks , and the RF model
there is a huge difference between the two models , the RF model is a normal model , but includes some additional network like substarte network , drain and source diodes and capacitances , gate resistance , gate induced noise effects ,
also the RF model is heavily dependent of the layout and fingering and gate contacts
