Abstract

The oscillator phase noise is one of the key limitations in several fields of electronics. An electronic oscillator phase noise is usually described by the Leeson's equation. Since the latter is frequently misinterpreted and misused, a complete derivation of the Leeson's equation in modern form is given first. Second, effects of flicker noise and active-device bias are accounted for. Next the complete spectrum of an electronic oscillator is derived extending the result of the Leeson's equation into a Lorentzian spectral line. Finally the spectrum of more complex oscillators including delay lines is calculated, like opto-electronic oscillators.

李森方程的扩展

振荡器相位噪声是电子领域的主要限制之一。电子振荡器相位噪声通常用李森方程来描述。由于后者经常被误解和误用，本文首先给出现代形式的李森方程的完整推导。其次，考虑了闪烁噪声和有源器件偏置的影响。然后，将李森方程的结果推广到洛伦兹谱线，导出了电子振荡器的全谱。最后计算了包括延迟线在内的更复杂振荡器的频谱，如光电振荡器。
