I don’t think there’s any difference in the two models-under-simulation, but never know if overlooked anything… Or, how can I debug what’s going with .bode analysis?
Here is the modification that allow .bode to run for your circuit. It seems to me that if IC is used in capacitor, .bode will run into problem (bug?), I will copy this to Mike for review.
Beside of that, you have to add .option bodeampfreq=0… this can force perturbation signal constant over frequency. With multiple change listed in the note in simulation file, simulation can be completed in about 15s in my laptop.
[Update : Mike fixed the problem of using instance parameter IC in capacitor for .bode 10/10/2024 Corrected an error regarding instance ICs on capacitors during a .bode analysis]
As bode got a high Q, you can tighten frequency response analysis relative tolerance (.option BODETOL), with longer simulation time, about 90s in my laptop.
I don’t have any insider information about which feature will be implemented next.
If you simulate this circuit from 100Hz, just use the default BODETOL. A .bode analysis between 100 and 100KHz (3 decades) takes about 4 minutes on my laptop with the default BODETOL=10. Avoid running .bode with frequencies over 3 decades, as it can significantly increase simulation time based on my experience.
