Hi guys,

I am trying to test the stability of the closed-loop boost converter using spectra. To simplify my question, let me assume there are only error amplifier and boost in this loop. The two inputs to the error amplifier are bandgap voltage and the feedback voltage from the boost converter output voltage divider. I can build up the boost and error amplifier small signal model. Can I use the spectra stb function to test the stability of this closed-loop?

Thanks.
 

yes, it is a good topic.
while, i simulate the stability just verilogA
actually, stb is a real thing.

anyone knows?
 

How to test the stability of the closed-loop boost with simulink ?
