Vertical BJT in 0.18um technology (VBIC)???

rbmod spectre model

Hello,
I have been trying to make this Bandgap circuit in Cadence and simulate it using Spectre. I managed to get some BJT parameters from somewhere, which I am using. The parameter block for the BJT is:

model wp2 bjt type=pnp is=1.229e-17 eg=1.169 xti=2.200 nf=1.010
+ ise=5.631f ne=1.740 ikf=5.363m vaf=16 bf=31 xtb=1.280 nr=1
+ isc=4.426e-16 nc=1.500 ikr=2.379m var=3.100 br=15 rc=276.231
+ trc1=2.31m trc2=13.691u re=2.647 tre1=250u tre2=0 rb=107.091
+ trb1=1.189m trb2=6.681u rbm=85.673 irb=3.413m cje=33.637f
+ mje=500m vje=990.003m fc=950m cjc=56.905f mjc=310m vjc=800m
+ xcjc=350m cjs=126.721f mjs=400m vjs=790m tf=16p tr=36n xtf=1
+ vtf=1.200 itf=2.454m ptf=25 kf=6.600e-16 af=1

But I think these parameters do not represent the BJT for the 0.18um process. I need the parameters for the BJT urgently. I searched MOSIS' website also but it only had parameters to PMOS and NMOS transistors. How or where do I get the parameters for the BJT from??

Any help would be greatly appreciated.

pnp5 vertical pnp

TSMC provides 3 BJT models NP10, PNP5, PNP2 for it's 018um process.

PNP10, PNP5, PNP2 - means emitter size 10X10, 5x5, 2x2.

You can find this in Log018m.scs file, section bip or bip3.

Where do I get the file Log018m.scs ????

Hi,
this is TSMC018mm NPN BJT models for 3.3V for Cadence.

You mean in Cadence? Could you please specify the name of the Folder? Thank you.
