A 5.0-to-6.36GHz Wideband-Harmonic-Shaping VCO Achieving 196.9dBc/Hz Peak FoM and 90-to-180kHz 1/f3 PN Corner Without Harmonic Tuning

📋 论文概要

该论文提出了一种5.0至6.36GHz的宽带谐波整形VCO，通过改进共模谐振技术实现了196.9dBc/Hz的峰值FoM和90至180kHz的1/f³相位噪声拐角，解决了传统LC VCO在宽带范围内相位噪声性能与面积效率之间的权衡问题。

💡 主要创新点

• 提出了一种宽带谐波整形技术，通过优化共模谐振网络在2倍振荡频率处的阻抗特性，显著降低了1/f³相位噪声拐角。
• 采用改进的脉冲灵敏度函数（ISF）整形方法，在不增加额外线圈面积的情况下实现了更优的相位噪声性能。

Instituto Superior Tecnico/University of Lisboa, Lisbon, Portugal 1 2 Since 2001 [1], LC VCOs have been demonstrating significant improvements of figureof-merit (FoM) and 1/f3 phase noise (PN) corner [2-5] by exploring common-mode (CM) resonance at twice the oscillation frequency (2FOSC). In addition, for area reduction, the shaping of the impulse sensitivity function (ISF) has evolved from explicit with two coils
