The probability distribution and the autocorrelation function of the fluctuating output voltage of a Wien-Bridge oscillator have been measured as a function of the feedback factor β. It has been found that both the variance and the correlation time of the fluctuation which are determined from the probability distribution and the correlation function, respectively, become infinite in a manner like (β_c-β)^<-1> as β approaches the threshold β_c of the oscillation. The aspect is analogous to the Curie-Weiss law in the second-order phase transition. The results are discussed within the linear response scheme starting from a simplified kinetic equation for fluctuating output voltage of the Wien-Bridge oscillator.
