Re: RF Modeling
RF modeling of the MOS transistor is a complicated issue
the bsim3v3 model is not RF model
RF model must include substarete network , which contain 4 dioodes : these diodes model the source drain junctions in high frequncy also the substarte network include 4 resistors , these elements must be caluculated and added to the BSIM3v3 model , to get the RF model
some models consider NQS resistance of the channel , and gate resistence
and in ver high frequency some models calculate gate inductance
check this presentation it may be helpfull
