I have found something useful in cadence community.

Noise Summary Example
For a MOS transistor, the individual noise contributors are fn, id, rs and rd.

-fn is the flicker noise

-id is the drain-source resistance thermal noise

-rs is the source parasitic thermal noise

-rd is the drain parasitic resistance thermal noise

For Bipolar transistor, the noise contributors are in rb, ib, rc, ic, fn, re,

and bn.

-rb is the base resistance thermal noise

-ib is the base current shot noise

-rc is the collector resistor thermal noise

-ic is the collector current shot noise

-fn is the flicker noise

-re is the emitter resistor thermal noise

-bn is the burst noise

-itfz is forward transport current

-ibe(A) Intrinisic B-E Junction Current

-kfn is B-E flicker noise constant

-afn is the B-E flicker niose exponent

-bfn is the B-E flicker noise dependence

For VBIC, (please also see Solution 11603018 )

- fn is the flicker noise between the node bi and ei.
- fnp is the flicker noise between the node bx and bp.
- fnx is the flicker noise between the node bx and ei.
