Observing multiple loop points in Cadence ADE Spectre stb analysis

[danvilla]

When running stb analysis, I would like to see the bode response not just for the entire loop but for some intermediate nodes to figure out how much gain/phase each stage in the loop is giving me. I have not been able to find how to do this in Cadence ADE.

for checking the intermediate gain & phase plots you can run ac analysis using 3 amp structure or using the res bias.

Here you need to ensure that the loop bias is maintained properly.

In 3 amp structure, 1 amp is used for bias other for load and the other will be tested
