How to add (white) noise in OrCAD simulation?

[a3abdelhafez]

hai for all

i want to ask qustion in orcad simulation

i want to add noise in my simulation
i want to add white noise in orcad

or iwant to generate white noise from source

You can add noisy resistor but in AC simulation ..

That noisy resistance may have white noise associated to it..

But i don't know how can you use it in any other simulations such as transient analysis..

Hope that helps,

Make new simulation profile,

Choose type: AC/Noise simulatin

Mark the "noise analysis" box --> Enabled

You can put parameters like in here:

Also you may find the attached paper useful to you..
