The study of the relation between Rn-Gn noisemodel and En-In noise model of an amplifier

摘要

The Rn-Gn noise model can only be used in the case of microwave low-noise amplifier design. Its application scopes are limited and in particular, it cannot be used in low-frequency low-noise amplifier design. This paper has adopted the En-I n noise model with spectral correlative coefficient (SCC) so that it can be used not only in high-frequency and narrow-band, but also in low frequency, source reactance, and wide-band amplifier low-noise design. In this paper, the equivalent relation between the En-In noise model and the Rn-Gn , noise model is derived, and the measurement method of the En-In noise model parameters and the measurement results are given. The Rn-Gn, noise model parameters can be accurately obtained by use of the equivalent relation
