shot noise

Shot noise, also known as current noise, is caused by the discrete nature of charge carriers as they pass through a voltage threshold.

Shot noise can be understood as the pattering of electrons and holes that occurs when a direct current flows and the charge carriers pass voltage thresholds, as in diodes or transistors.

Shot noise is white noise because the spectral noise density is the same across all frequencies.
