论文摘要
本文探讨了振荡器稳态的对称性与幅度和相位变量在小信号状态中的正交表示有关的先前未知的连接。结果表明,只有产生完美对称稳态的电路才能产生正交的浮子分解。考虑室温操作,这种情况意味着零AM-PM噪声转换。这种令人惊讶和新颖的结果直接源于本文首先描述的严格模型框架的预测。本文中介绍的工作扩展了当前的最新W.R.T.振荡器的小信号/噪声表征。
The paper explores a previously unknown connection relating the symmetry properties of an oscillator steady-state to the orthogonal representation of amplitude and phase variables in the small-signal regime. It is shown that only circuits producing perfectly symmetric steady-states can produce an orthogonal Floquet decomposition. Considering room temperature operation this scenario implies zero AM-PM noise conversion. This surprising and novel result follows directly from the predictions of a rigorous model framework first described herein. The work presented in this text extend the current state-of-the-art w.r.t. oscillator small-signal/noise characterization.
