该论文提出了一种28GHz可扩展芯间整形多核振荡器，通过DM/CM配置耦合技术实现优异的相位噪声性能。解决了毫米波通信中本振相位噪声要求高和功耗优化的问题，实现了193.3dBc/Hz的高FoM。
The high-order modulation schemes of mm-wave wireless communication networks (e.g., 5GNR) have stringent requirements for the LO phase noise. Besides, to minimize the power consumption of oscillators, a high figure-of-merit (FoM) is targeted, especially for the very-low-phase-noise specifications. Various harmonic-shaping techniques have been reported to reduce the noise sensitivity [1-3], and thus improve the FoM. By utilizing the mutual coupling of an inductor and a single-ended capacitor, the implicit commonmode technique [1] can set the common-mode (CM) resonance at 2fLO without an extra CM resonator. Then, the phase noise degradation due to the triode operation is eliminated, while the flicker noise upconversion can be minimized. However, the mutual coupling k pushes CM to a higher frequency by cancelling the magnetic flux, which reduces the inductor quality factor (Q) in CM by a factor of 1-k, as shown in Fig. 8.3.1top-left. Meanwhile, the Q of the single-ended switched capacitor
