periodic ac analysis in mentor design architect-ic

Question asked by e3402 on Mar 13, 2019

Hi all,


I'm using mentor design architect v2008.2_7.1 to simulate a switched capacitive filter. As you know, I need to utilize periodic AC analysis rather than "normal" AC analysis. Even if there are some provided macro models for switched capacitive filter analysis but it is not possible to modify all parameters of them. (For example, I could not find a way of setting Rin or Roff resistance of proposed switches.) Is there a method to set PAC(periodic AC analysis) by using voltage controlled switches and ideal capacitances? For the sake of clarity I'm also adding a very simple filter I would like to simulate.


Thanks in advance,
