hi,
i am trying to calculate the phase noise for a frequency divider that we have designed in cadence. when i look for any tutorial on the web, all of them talk about phase noise of an oscillator. i got one document on the designer's guide though - which talks about the phase noise model of a divider. it says that one should do pss on the divider and then the pnoise analysis. but i am confused about what values do i need to give to different parameters like beat frequency, output harmonics etc. while doing the pss analysis my pss analysis terminates due to error saying that it doesn't converge.. all i am looking for the steps (actually the babysteps) to do the pss and pnoise analysis on the divider with information about the values to be given in different boxes i am using cadence spectre for the project. can anyone please help me?
thanks
