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

Raveesh

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

Raveesh

    Reveesh,

    This will depend on the simulator (which simulator are you using?), and also the type of device (the model type) that is being used. For example, bsim4 has different parameters to a mos902 to a bjt and so on. I don't recall any noise parameter called "sh" though in any model - but if you can state the simulator and model type that is being used, we might be able to work it out.

    You can see the model type names used in your design on the Results->Print->Noise Summary form - it will list the types of components that you have to allow you to filter the results to only see the noise from certain types of device.

    Regards,

    Andrew.
