This is an amazing video about how to analyse noise in LT spice . Neatly explained! this is a good refresher of concepts learned in University. Thanks for making such content. Keep the good work coming
Hi, resistor R1 has thermal noise which can be modeled as a voltage source in series with R1. The opamp configuration that looks like that (voltage source + resistor to the inverting input and a resistor from output to the inverting input) is an inverting amplifier. The inverting amplifier has a gain formula of gain = -R2 / R1. Which is - 100k / 10k = -10
Intriguing! Hmm. A bit too complicated for my tiny brain cell. I see if I could imitate this in Multisim. I hope my free version of Multisim works well for this case.

great content but I am not able to understand how gain is 10 wrt to the ground resistor @3:13

@@trevortjes ok. Now I got the point. Thanks!!
Please upld more vids.
