# 相噪评估
|
|||
|
|
**基底噪声**：
|
|||
|
|
$PN_{floor} = Floor FOM + 20 * log(Fvco/Fpd) + 10 * log(Fpd / 1Hz)$
|
|||
|
|
|
|||
|
|
**$1/f$ 噪声**：
|
|||
|
|
$PN_{flick} = Flick FOM + 20 * log(Fvco/ 1Hz) – 10 * log(offset / 1Hz)$
|
|||
|
|
|
|||
|
|
**总噪声**：
|
|||
|
|
$PLL_{noise} = 10 * log(10^{PN_{floor} / 10} + 10^{PN_{flick} / 10} )$
