5 Noise Measurements
The noise model is shown in
Figure 33
, where:
z
eN: input voltage noise of the amplifier
z
iNn: negative input current noise of the amplifier
z
iNp: positive input current noise of the amplifier
The thermal noise of a resistance R is:
where
F is the specified bandwidth.
On a 1Hz bandwidth the thermal noise is reduced to
where k is the Boltzmann's constant, equal to 1,374.10-23J/°K. T is the temperature (°K).
The output noise eNo is calculated using the Superposition Theorem. However eNo is not the simple sum
of all noise sources, but rather the square root of the sum of the square of each noise source, as shown
in
Equation 1
