摘要

本文讨论了基于导纳/阻抗算子和传递函数表示等线性概念的面向电压电流的方法扩展功率波公式的必要性。讨论了在整个功率波公式中,多物理场方法对晶体振荡器分析和设计的重要性。提出了用类旋涡行为来解释微分交叉耦合VCO体系结构的分岔模式。强调了幅值水平控制(ALC)对大信号相位噪声性能的影响,显示了相对于功率-能量考虑的鲁棒控制分析方法的必要性。

Power waves formulation of oscillation conditions: Avoidance of bifurcation modes in cross-coupled VCO architectures
This paper discusses necessity of power-waves formulation to extend voltage-current oriented approaches based on linear concepts such as admittance/impedance operators and transfer-function representations. Importance of multi-physics methodologies, throughout power-waves formulation, for the analysis and design of crystal oscillators is discussed. Interpretation of bifurcation modes in differential cross-coupled VCO architectures in terms of gyrator-like behavior, is proposed. Impact of amplitude level control (ALC) on large-signal phase noise performances is underlined showing necessity of robust control analysis approach relative to power-energy considerations.
