Shot Noise characteristic is white.
"2. Shot Noise
Shot Noise normally occurs when there is a potential barrier (voltage differential).
PN junction diode is an example that has potential barrier. When the electrons and holes cross the barrier, Shot Noise is produced.
For example, a diode, a transistor, and vacuum tube, all will produce Shot noise.
A junction diode will typically have two components of noise. One is Thermal Noise, and the other is Shot Noise.
Note that if the active device provides amplification, the noise also gets amplified along with the signal.
On the other hand, a resistor normally does not produce Shot Noise since there is no potential barrier built within a resistor. Current flowing through a resistor will not exhibit any fluctuations. However, current flowing through a diode produces small fluctuations. This is due to electrons (in turn, the charge) arriving in quanta, one electron at a time. The current flow is not continuous, but limited by the quantum of the electron charges.
Shot Noise is proportional to the current passing through the device.
Shot Noise characteristic is white."
