Nature of 1f Phase Noise
Abstract
The quantum theory of 1f noise developed in the preceding Letter is extended by showing that because of interaction with the electromagnetic field, an alternating current carried by a beam of electrons emerging from some scattering process will present phase fluctuations with a 1f spectrum. These fluctuations are expected in any ac current. They have similar power spectra, also determined by infrared radiative corrections, to dc 1f noise.
