hello:
I have acquired the physical parameters of MOSFET from TSMC PDK model XXX.scs file.
it appears like this:
model nch bsim4 {
1: type=n
+ lmin=9.999997e-006-(dxln+dlmisn) lmax=2.00001e-05
+ wmin=1e-005-(dxwn+dwmisn) wmax=0.0009000001 version=4.5
+ gbmin=1.00e-12 rbsb=50 ud=0
+ rbdb=50 rgeomod=1 rbpb=50
+ rshg=1.539650e+01 rbps=50 rbpd=50
+ ngcon=1 binunit=2 paramchk=1
+ mobmod=0 capmod=2 igcmod=1
+ igbmod=1 diomod=1 rdsmod=1....................this is just a slice of the whole definition
I am trying to get the design variables such as Cgs, Cds, gm, Id, and etc. which I can get from ADE browser. right now, I need the equations that could link the physical parameters to these regular design variables. I have looked up the MMSIM151 doc: spectremod:Virtuoso ® Simulator Components and Device Models Reference. it says that "The TSMC Model Interface (TMI) implements a modified version of the BSIM4 model, known as TMIBSIM4." in page 1317. my question is where can i get the TSMC model equation. thanks in advance.
