mit noise simulation
Hello,
I need to do a noise simulation with a fully differential OP-AMP with CMFB.
The first stage is a Folded Cascode Amp, the second a Class AB Stage.
The CMFB Amp is a simple OTA.
My question: I use SpectreS, the noise simulation need as parameters the positive and negative output node and the input source. Well, do I have to simulate every input separate or both together with a voltage source between the two input nodes?
If i have to do the simulaten separate for both input nodes, which nods do I choose for the negative and positive output nodes in the simulation options?
Thanks!
Alex
