โœฆ Synopsis

This paper presents a method to analyse noise in cascaded non-linear stages based on Volterra series for multiport systems. The cascaded stages are partitioned such that internal noise sources from different stages are uncorrelated and linear loading between all stages can be assumed. This partitioning scheme implies that the ensemble average of the magnitude-squared output response from the last stage in the cascade can be determined as a sum of noise contributions from the individual stages. The method allows both unmodulated (independent) and modulated (dependent) noise sources. A special case of the theory and two related examples are presented to illustrate the method.

The physical assumptions on which linear uctuation theory is based do not apply to internal noise in non-linear systems. As a consequence, there is still no complete theory for internal (thermal) noise in non-linear electrical networks. In this paper the authors apply Stratonovich's 'non-linear non-
