Hi odyseus (and all),
In your Feedback Oscillator Design Tutorial, how did you plot the group delay and loaded Q of the resonator? I find no way in ADS to do this. According to the ADS document, a function named 'delay()' is to calculate the group delay, but I can't use it in an Eqn. It seems to be used as a Simulator Expressions and in a VarEqn, but I can't find VarEqn neither :(
Pleas help me!
Thanks a lot!
 

i think in the sp simulator controller there is a check box , called group delay
check it

then u can plot it

khouly
