Title: Modelling a White-Cyclostaionary Current Noise source in VerilogA
Post by Ricky Chen on Jul 5^th, 2013, 10:17pm

Dear All,
I want to model a Cyclostaionary White Noise current source.
It will be something like :- I = 4*K*T * W(t).
Where W(t) a periodic wave ( let's say a periodic Square Wave).

Also I want to use this modelled Noise current source for use in my RF circuit fro PSS/PNOISE analysis.

Could anybody please tell how to write the code for it ?

Kind Regards,

Did you try something like

wfunc = W($abstime);
I(a,b) <+ white_noise( 4 * `P_K * $temperature * wfunc );

?
