On the Origin of 1/f Noise due to Generated Entropy - Version 2

Authors: Alec Feinberg

Noise measurements analysis has been associated with degradation. In particular one such noise type called 1/f noise is likely the leading indicator. It is important to identify the noise frequency region of the spectrum associated with degradation occurring in materials to aid in noise type of reliability tests. The literature on 1/f noise appears to have a broad commonality in explanations and models related to degradation between materials and the measurement environment. It is reasonable in this regard to look at 1/f noise aspects in a broad sense in terms of disorder and the associated spectral content. This lends itself to a thermodynamic entropy framework for analysis. We review some of the key aspects of 1/f noise in the literature and discuss how observations relate to entropy. Once describe, we then suggest two thermodynamics models that one might use to model 1/f noise. Results help to provide a broader understanding of 1/f noise by using a different framework in terms of thermodynamic degradation processes. Such interpretation suggests that 1/f noise is a good tool for measuring certain aspects of disorder in materials and likely the associated spectral signatures. Experiments are suggested to demonstrate the importance of 1/f noise as a prognostic tool for 1/f noise reliability testing to identify and predict degradation in materials over time. We also suggest using standardized spectral identification methods.
