Shot Noise in Amplifiers (Amplifiers #14)

The discrete nature of electric charge - the electron - can result in shot noise. Let's see practically what this means for circuits.

Thank you for posting these videos. Super helpful for my reviews.

Good explanation and vivid clarification on shot noise. Keep going and updating teaching materials, thx!

I thought shot noise is more related to crossinng of pn junctions, & depletion areas. Also, You state for a large current it is irrelevant,, but the equation governing it is 2qI and this is just a fixed ratio with current - so relative stays constant. In MOS devices, in the channel in inversion/saturation it is not modelled as shot noise but more as thermal noise. Main question I have is if shot noise is ALWAYS related to the move of electrons due to Electrical field (voltage) or does it not happen in a resistor for example that carries a DC current?
