Ultralow Noise Amplifier
Added 2020-08-16 20:33:27 +0000 UTCNot sure what happened here đ€ this project started as 'ts80p.prproj' but the soldering iron didn't offer a whole lot of talking material. So instead I started rambling about noise ... for 25 minutes ...

Seen it! A very sophisticated solution whereas I am just relying on good opa performance :)

2021-03-02 10:50:12 +0000 UTCA colleague of mine built a low noise amp which goes down to 1/10Hz and he didn't use any fancy tantalum caps so maybe you can do the same đ

2020-08-24 17:07:23 +0000 UTCYou could use a two stage design for your amplifier, you can dimension the first stage that even with the worst leakage current of you cap you don't hit the supply rails and then use a second dc block with a higher gain amplifier afterwards that way you won't have that much leakage anyways because you've got a lower dc bias đ€

2020-08-19 09:16:29 +0000 UTCIt got even more ambitious than I originally wanted it to be đ It's a team effort now, happening mostly on the discord server. It'll take a lot longer, but it will be worth it. This power output stage is one of multiple candidates we are considering https://github.com/marcoreps/lt1166_bob

2020-08-17 19:59:04 +0000 UTCBased on my display of expertise here? đ I bet others could do that a lot better
