Abstract

This letter presents a fully-integrated 2-bit CMOS voltage-controlled oscillator (VCO) along with a 2-bit buffer, which delivers the highest RF output power among recently reported state-of-the-art to the best of the authors’ knowledge. The proposed 2-bit VCO is designed and fabricated in a

CMOS process with a die size of 1.2 mm

$\times$

1.2 mm, which covers four frequency bands of interest. Fine-tuning at each of the four frequency bands is also obtained by utilizing two varactors. The proposed 2-bit VCO delivers a single-ended output power of 6.5/6.8/10.6/12.5 dBm at 0.930/1.157/1.436/1.917 GHz, respectively. This 2-bit VCO can cover frequency ranges of 930–1005, 1046–1157, 1248–1436, and 1540–1917 MHz, thus providing a total frequency bandwidth of 751 MHz. The proposed 2-bit VCO at each frequency band demonstrates −99, −93, −90, and −86 dBc/Hz for phase noise, and −150, −150, −160, and −168 dBc/Hz for figure-of-merit (FOM), respectively.

用于多波段无线应用的2位压控振荡器(VCO)

这封信介绍了一个完全集成的2位CMOS压控振荡器(VCO)和一个2位缓冲器，据作者所知，它在最近报道的最先进的技术中提供了最高的RF输出功率。所提出的2位VCO是在$0.18-\mu \text{m}$ CMOS工艺中设计和制造的，其芯片尺寸为$ 1.2 mm $ × $ 1.2 mm，涵盖了四个感兴趣的频段。在每个四个频段的微调也得到了利用两个变容器。所提出的2位VCO在0.930/1.157/1.436/1.917 GHz时的单端输出功率分别为6.5/6.8/10.6/12.5 dBm。这个2位VCO可以覆盖930-1005、1046-1157、1248-1436和1540-1917 MHz的频率范围，从而提供751 MHz的总频率带宽。所提出的2位VCO在每个频段的相位噪声分别为- 99、- 93、- 90和- 86 dBc/Hz，品质因数(FOM)分别为- 150、- 150、- 160和- 168 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.
