Application of Chaos Theory to 1/f Noise
Abstract
1/f noise limits the sensitivity of HgCdTe photodiodes operated in the low frequency staring mode. Because other theories have failed to account for 1/f noise as a general phenomenon, the applicability of chaos theory in this material is investigated. 1/f noise data from HgCdTe photodiodes are applied to the analytic technique of R. Grassborger and I. Procaccia. Analysis indicates that a chaotic phenomenon underlies the 1/f noise. Construction of a model of 1/ f noise in HgCdTe photodiodes consistent with the principle of chaos theory and the body of experimental knowledge about this phenomenon is begun. Initial model produced a 1/f to the alpha power noise spectrum with alpha having a value close to 2. Keywords: Photodiodes; Mercury cadmium telluride.
