Abstract

In this letter, low-phase-nose multicore class-F voltage-controlled oscillators (VCOs) using coupled-lined-based synchronization topology are proposed. Compared to traditional resistance-coupled multicore VCOs, the proposed coupled-line-based topology improves the $Q$ of the small inductors in the millimeter-wave frequency range. Mode ambiguity is eliminated for a robust oscillation startup. Quad-core and oct-core VCO prototypes are designed and implemented in 65-nm CMOS process, which exhibit a measured frequency tuning range of 20.5% centered at 31.32 GHz. The quad-core VCO has a measured phase noise (PN) of −134.33 dBc/Hz and a corresponding FoM of 191.32 dBc/Hz at 10-MHz offset from 28.28 GHz. The oct-core VCO has a measured PN of −137.23 dBc/Hz and a corresponding FoM of 191.08 dBc/Hz at 10-MHz offset from 28.16 GHz.

基于耦合线路同步拓扑的30GHz低相位噪声可扩展多核F类压控振荡器

在这封信中，提出了使用基于耦合线同步拓扑的低相鼻多核f类压控振荡器(vco)。与传统的电阻耦合多芯压控振荡器相比，本文提出的基于耦合线的拓扑结构提高了毫米波频率范围内小型电感器的Q值。消除了模态模糊，实现了鲁棒振荡启动。四核和八核VCO原型在65纳米CMOS工艺中设计和实现，其测量频率调谐范围为20.5%，中心为31.32 GHz。该四核VCO在28.28 GHz的10mhz偏移处的相位噪声(PN)为- 134.33 dBc/Hz，相应的FoM为191.32 dBc/Hz。该八核VCO在28.16 GHz的10mhz偏移处的PN值为−137.23 dBc/Hz，相应的FoM值为191.08 dBc/Hz。

期刊介绍： The IEEE Microwave and Wireless Components Letters (MWCL) publishes four-page papers (3 pages of text + up to 1 page of references) that focus on microwave theory, techniques and applications as they relate to components, devices, circuits, biological effects, and systems involving the generation, modulation, demodulation, control, transmission, and detection of microwave signals. This includes scientific, technical, medical and industrial activities. Microwave theory and techniques relates to electromagnetic waves in the frequency range of a few MHz and a THz; other spectral regions and wave types are included within the scope of the MWCL whenever basic microwave theory and techniques can yield useful results. Generally, this occurs in the theory of wave propagation in structures with dimensions comparable to a wavelength, and in the related techniques for analysis and design.
