摘要: 從 A.Van der Ziel(1976)提出的電流電壓方程出發(fā),導(dǎo)出一個(gè)歸一化擾動(dòng)量微分方程。將歸一化擾動(dòng)量的傅氏變換按j的冪級(jí)數(shù)形式展開并且求解,得到在漏、柵端擾動(dòng)量傅氏變換的各階解析解,同時(shí)也就得到了漏、柵極的噪聲電流譜和相關(guān)系數(shù),在結(jié)論中,指出了方程的高階解對(duì)噪聲譜的影響。

Abstract: Starting from the current-voltage equation given by A. Van der Ziel (1976), a dif-ferential equation of the normalized fluctuation is developed. Expanding the Pourier transform of the fluctuation into a power series in the parameter j and solving the equation developed, we get all order analytical solutions of the Fourier transform of the fluctuation in drain and gate. The spectral desities of noise current of drain and gate as well as the correlation coefficient are also obtained. The effect of the higher order solutions of the equation on the noise spectra is shown in the conclusion. -
