Abstract :
In this paper, a new matrix-based approach for differential noise figure measurement will be presented. Passive components used for embedding a differential device into a single ended test setup are characterized by their noise correlation matrices. Then, signal transfer via the component chain is described by chain matrices. Determining the output referred noise correlation matrix of the device under test this way, a noise figure can be denoted.
