Table 11 Noise types by device type
Device type Noise types*
* These variables report the contribution of the specified device’s noise to the total output noise in units of V
2
/Hz. This means
that the sum of all device noise contributions is equal to the total output noise in V
2
/Hz, NTOT(ONOISE).
