Leeson's equation : ウィキペディア英語版 | Leeson's equation Leeson's equation is an empirical expression that describes an oscillator's phase noise spectrum. Leeson's expression for single-sideband (SSB) phase noise in dBc/Hz (decibels relative to output level per Hertz) is〔, p. 115.〕 : :where ''f''0 is the output frequency, Ql is the loaded Q, ''f''m is the offset from the output frequency (Hz), ''f''c is the 1/''f'' corner frequency, ''F'' is the noise factor of the amplifier, ''k'' is Boltzmann's constant, in Joules/Kevin , ''T'' is absolute temperature in Kelvins, and ''P''s is the output power.〔https://books.google.com/books?id=pTqI98FJYlYC&pg=PA299&lpg=PA299&source=bl&hl=en&f=false〕 ==References==
