Title: AC simulation in ADS2004
Post by Turin on May 5^th, 2009, 9:06am

Hi everyone,

I'm trying to do a AC simulation on an integrator in ADS2004. But I'm still not sure i understand what parameters to put on the I_AC source to give me the right diffenrencial input I need....Does anyone who used ADS have any suggestions...

The intergrator....

This question is same as the following your post.

Your question is not specific for ADS.
I can't understand what you are confusing.

Why do you connect "I_AC" and "Term" in series ?
And why do you use "Term" as load of output nodes ?
If you don't do SP-Analysis, you don't have to use "Term".

Usually I use one of the followings as input drive signal.
(1) "P_AC"
(2) Parallel connection of
"I_DC" or "I_AC" and
　　　　"Resistor" or "Z1P_Eqn" or "Y1P_Eqn" or "S1P_Eqn" or "Term"
(3) Seriers connection of
"V_DC" or "V_AC" and
　　　　"Resistor" or "Z1P_Eqn" or "Y1P_Eqn" or "S1P_Eqn" or "Term"

You can do the following by using any vendor's simulator.
