Is noise included in transient simulation done in Cadence?

[surianova]

hi all!

is noise ( thermal noise,fliker noise and shot noise) include in transient simulation in Cadence? I agree it show in AC noise analysis which have 40 uv RMS in my opamp.. but i can't see it in transient simulation. The output is flat or noiseless regarding any temperature. If noise never show in transient, how can model it?

thanks..

spectre transient noise how to

There is no noise in transient analysis.

There is no noise in transient analysis.

if i have input referred noise of 10 uv rms in ac noise analysis, is it no way to model it in transient?

Define a noise signal in time domain and connect it to the input.

actually until now i am still can't get a good answer. .some say yes and some say no..

or is it depend on the software tool we use?

Well, in more or less recent versions of spectre there is an option for transient noise while tran. It wasn't there a couple of years ago..Personally I have never tried it ..

what is the option? can you tell us? THKS!

Spectre transient noise works quite well. You can simulate whatever you like with it. What exactly you want to know?

How you view the noise in transient?
