Abstract

In this work, we propose a 24-GHz VCO using a transformer. In the mm-wave band, parasitic components of the passive device and feeding line degrade VCO performance. To reduce the undesired effects of passive devices, we replaced the transformer instead of passive devices such as the inductor or capacitor. In addition, we propose a frequency tuning technique using a gate bias instead of a typical varactor. To verify the feasibility of the proposed structure, we designed the VCO using a 110-nm RFCMOS process. The measured frequency tuning range of VCO was 22.7 to 24.2 GHz, and it had output power of 8.4 dBm at 24 GHz. The measured phase noise was -95.33 dBc/Hz at 1 MHz, offset at an operating frequency of 23.6 GHz. The chip size was 370 × 380 μm2, including test pads.

采用栅极漏极磁耦合通过变压器的24ghz压控振荡器设计
在这项工作中,我们提出了一个使用变压器的24 ghz压控振荡器。在毫米波频段,无源器件和馈线的寄生元件会降低压控振荡器的性能。为了减少无源器件的不良影响,我们用变压器代替了电感或电容器等无源器件。此外,我们提出了一种使用门偏置代替典型变容管的频率调谐技术。为了验证所提出结构的可行性,我们使用110 nm RFCMOS工艺设计了VCO。VCO的频率调谐范围为22.7 ~ 24.2 GHz,在24 GHz时输出功率为8.4 dBm。测量到的相位噪声在1 MHz时为-95.33 dBc/Hz,工作频率为23.6 GHz时偏移。芯片尺寸为370 × 380 μm2,包括测试片。
