generation of noise in pspice

[vinaiece]

how to generate the noise in pspice ,is thr any circuit to generate the noise in pspice

 

[A.Anand Srinivasan]

try taking output from a switching thyristor or some other switching element....

I think this would be easier if you use ADS

In the real life, Zener diodes are usually used as noise generators (see, for example, this app note http://www.maxim-ic.com/appnotes.cfm/an_pk/3469). I don’t know if the Zener is modeled with noise in PSpice, but you could give it a try.

I would also like to invite you question to this group, which has some good OrCAD & PSpice experts: http://tech.groups.yahoo.com/group/OrCADexchange

Do you mean to generate a time domain random signal, with white noise spectrum?

Or do you just want to perform noise analysis?
