Dear all,

I want to  simulate the phase noise of my divider which take input differential clock source (ideal). Some phase recombinations circuits after the divider give me multiple phase outputs. I want to see the phase noise of each phase output

Can any body tell how can I do the phase noise simulation of my divider. ( please point to any suitable documents)

I want to do following simulations with the divider

1)  simulate without any phase noise  in the  clock

2) simulate with certain amount phase noise  in the  clock

3) Lastly, I want to make some trasnsistors of the divider NOISELESS and then do the phase noise simulation

I could make the flicker noise of desired MOS transistors zero but How can I make their thermal NOISe zero.

Andrew Beckett has just pointed out at http://www.cadence.com/community/forums/T/22011.aspx that it is in fact possible in Spectre to turn off or on the noise of specified devices.
