A method of identification of RTS components in noise signals

Noise signals containing two components with different distribution of current values of the noise signal, i.e. a component with Gaussian distribution and a component with non-Gaussian distribution, were analyzed. The non-Gaussian component was recognized as Random Telegraph Signal (RTS) noise. The method which enables RTS noise identification was presented. The results of an identification of RTS noise in inherent noise signals of type CNY17 optocoupler devices are included. The quality of the proposed method was verified on the base of histograms of two components of noise signal and on the base of the Noise Scattering Pattern (NSP) method.
