I am trying to do the thorough noise analysis of a simple inverter and a sense amplifier using Spectre. What type of input combination and signal should I provide for correct analysis? And what type of output load should I use?

Thank you for your time!

Thank you for your reply. Currently I am using 4 cascaded inverters with a 2fF load at the end and I am doing the same for sense amplifier (cascaded). My intention is to analyze the noise considering my circuits will be used to build a large logic family.

And also I am using very small supply voltage (which is almost close to threshold voltage of the transistors) to see noise effects at reduced supply voltage.

In my case, a smaller noise voltage(close to threshold crossing) might impact my circuit behaviour. For sense amplifier, I am interested to use double-ended outputs to drive following stages.

Should I still do the jitter analysis and what should I do for sense amplifier?

Thank you for your time.
