How I can disable the thermal noise contribution but enable flicker noise contribution of MOS device

Dear All,

Could anybody please suggest me how I can disable the thermal noise contribution but enable flicker noise contribution of MOS device ?

Kind Regards,

Parents

Have you tried Options -> Analog -> Main tab -> NOISE OPTIONS?

You can specify individual devices to turn on/off different noise source types (or all). I found that if you don't specify specific devices and just select one of the types, such as flicker noise, in the "noiseon_type" section then it applies to all devices and only turns on that noise type.

Dear RFStuff,

If it is of interest to you, there are some subtleties to using the various radio buttons in the NOISE OPTIONS tab which livingstone referred you to. If you are not familiar with them already, I happened to assemble a short note that details some of them at URL:

I thought I might pass this along if it happens to be of any interest RFStuff.

Dear RFStuff,

I should have included the context from which I generated that note as there is some discussion about enabling and disabling various noise sources - sorry! The Forum post was:
