If Vout is an output , how can I express Vout(10KHz) in ADS ???
 

if the start frequency is 10KHz then you can get the value by Vout[0]
if the start frequency is some thing different then
set it as per the frequency points

Yeah~~~3Q^!^

Could you explain that more particularly~

the start frequency is 0,and the stop frequency is 10MHz, step=10Hz ....What is the expression of Vout(10KHz) ??
 

use a function what(Vout) in data display. I twill show the dependency, how many points, type etc.
for your data use the expression freq[1000] then it should show 10kHz.
if not then adjust to freq[1001 or 999] then it will definitely show as 10KHz.
Put this the number in Vout[999 or 1000 or 1001] to get the required 10KHz response.
 

Thank you!! Your answer is very useful~~

The attached document is my ADS2008 Project . I want to set the (Phase_Margin)max at 10KHz , but I don't know how to config the Goal.(the current (Phase_Margin)max is at about 1KHz ,see datadisplay)

could you help me to modify the Project ??
 

Thanks for giving clue~~ I have work out ~~~

There is a variable called as"UnityGainFreq"
You can change your frequency at which the pahse margin should optimized.
