According to our studies, the output transistor 1/f noise can be characterized more accurately as non-Gaussian ¦Á-stable distribution rather than Gaussian distribution. We define and consistently estimate the samples normalized cross-correlations of linear S¦ÁS processes and propose a samples normalized cross-correlations¨Cbased ¦Á-spectrum method effective in noisy environments.
