what properties matter in your circuit?

I'm focusing on noise simulations, I would use lithium battery, but I do a soft start and a capacitor in parallel is not a good idea

Wow !

Thanks a lot !

mostly I just use back of the envelope calcs and the datasheets - and I have designed electronic device noise limited interfaces for many types of transducers professionally - never looked like spice .noise analysis could help - really limited by the real part performance and the system noise from layout, ps, gnds...

Never able to make a decent noise simulation, it seems to me that mathematical models are incomplete in that issue.

Me too I deal with .tran and .ac

However, my knowledge is pretty limited, almost as much as my instruments.

Simulations are my walking stick. 😀

Thanks for your reply.

20 secs on Google, here on diyaudio, on the previous page of this thread ;-)

Thanks!

Looked in Google for two days before writing on this thread, as it was old.

I found one sub files for LM339, but not 329. Was going to go the Yahoo group.

BTW: someone helped found the way to compute the exact value for the resistors in the super-regulator.
