Background noise and measurements - Theoretical aspects

The performance of electronic systems is increasingly limited by the noise behavior of both passive and active components. It is important for designers to have as accurate an assessment as possible of component background noise and to be familiar with existing measurement techniques and simulation models.

We have therefore focused this report and the next one on four main objectives.

The first objective addressed in this report is to quickly clarify the mathematical formalism and, from a theoretical point of view, the physical origin of the main sources of background noise, as well as how these sources are characterized within the framework of circuit theory.

The other three objectives will be developed in the dossier. .
