Which noise does param 'sh' stand for in ADE noise summary?

Hi,

I am doing verification of an LDO and I am a beginner. I was doing Noise analysis using Cadence ADE and in the Noise summary printed, there is a param called 'sh' for the type of noise. I would like to know exactly which noise type does it refer to?

Requesting help from somebody who knows the answer.

Regards

Hi Raveesh,
I did not see the noise parameter "sh" in the list of noise parameters when I ran a noise analysis. It may be a shot noise parameter whose abbreviation is truncated. Perhaps you are using a different version. I am using IC6.1.5.500.11. The abbreviations for the various noise parameters may be found at:

or as shown below.

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.
