You do fundamental errors..
-DC OP gives you "static" intrinsic parameters, not dynamic..Briefly it computes intrinsic parameters for given DC OP.
-s-parameters relate the Input and Output to "small signal" Transfer Function under the condition Ports are terminated by Zo, so intrinsic parameters cannot be accurately extracted with s-parameters..
-Intrinsic Parameters can be extracted ONLY and ONLY by Modelling Softwares such as ICCAP etc. You measure the active device, you obtain DC,AC,s-parameters,Load Pull Values then that software extracts the intrinsic parameters in a certain tolerance accuracy in according to given model.
This needs an experienced engineering knowledge.
