Hello,
Thank you so much for your reply, it definitely helps. And yes with Multisim, sometimes I face convergence issues for some values. So I will definitely follow your suggestion and try to check for transient analysis details. I am using AD8333 as the other I/Q demodulators have RF input range starting from 50MHz or 400MHz and for my application, I needed an IC that starts from lower values. Plus, when I started simulation, initially the Spice model of AD8333 was not available. Should I send you or upload my Multisim file so that you can get better overview? So that I can atleast be sure if I have correctly connected AD8333.
Regards,
