Abstract

In this paper, we present and discuss a general and modular semi-analytical analysis method for the electrical and the noise characterization of noisy linear four-port circuits. The analysis method presented builds upon the concept of noise correlation matrices and is valid for both two-port and four-port electrical networks. We also consider a four-port active transversal filter case study for which we compare the measured results with those obtained from the analysis presented here. The analytical results are in very good agreement with measured results.
