Abstract
We show that the linewidth of a Josephson flux-flow oscillator has the same functional dependence on temperature, static, and dynamic resistances as t he ones of Josephson single-fluxon oscillators and small Josephson junction s. This suggests a universal formula for the linewidth of Josephson oscilla tors.
