WebJan 17, 2024 · • Flicker noise, also known as 1/f or pink noise, is a low-frequency phenomenon, usually characterized by a Gaussian distribution. In resistors and FETs it is linear, while in BJTs and diodes it is non-linear. In carbon and thick-film resistors, flicker is called excess noise because it is higher in amplitude than thermal noise.
