Your comment looks like it disagrees, but actually you are both agreeing that thermal noise is not the only noise source and that other design factors matter. For other readers: some resistors have much lower flicker noise[1] where “wire-wound resistors have the least amount of flicker noise. Since flicker noise is related to the level of DC, if the current is kept low, thermal noise will be the predominant effect in the resistor, and the type of resistor used may not affect noise levels, depending on the frequency window.” https://en.wikipedia.org/wiki/Flicker_noise |
