This circuit has been taken from a "DIY Oscilloscope" project. This circuit is changing the input wave swing to 0V to 3.3V. The circled voltage source is Vsys/2, which is the voltage at which the zero level of the input wave will be shifted to. Vsys is 3.3V here.
The output is as follows:
I wanted to know how is this working and can I use it for my project?
The original circuit with Raspberry PI PICO is as follows.
Thank you.
Its not the best circuit ever but its definitely worth putting on a breadboard and experimenting with it.
With these magnitude of resistors in the feedback path you may find you need a tiny compensation capacitor for stability
On a breadboard you could just twist 2 insulated wire together to make your own, if need be.

You're Welcome. I have tried the pico with pulseview

I will have to try the Scoppy project you linked to in the future, thanks for sharing!
scottiebabe Yeah just twist 2 wires together.. 10 out of 10!! btw a nice wire to do this with is CAT5 or CAT6 as it is already twisted.
And I don't really do analog. But I used to build audio gear. feedback and noise.
Aww thanks, but I am a good 40 dBc below legends like https://www.teledynelecroy.com/walter-lecroy/ ( I just saw this :( )
