APPLICATION INFORMATION
noise calculations and noise figure (continued)
For more information on noise analysis, please refer to the Noise Analysissection in Operational Amplifier
Circuits Applications Report(literature number SLVA043).
This brings up another noise measurement usually preferred in RF applications, the noise figure (NF). Noise
figure is a measure of noise degradation caused by the amplifier. The value of the source resistance must be
defined and is typically 50
in RF applications.

Because the dominant noise components are generally the source resistance and the internal amplifier noise
voltage, we can approximate the noise figure as:
