Abstract

This paper presents the design and measurements of a 215-252 GHz 40 nm bulk CMOS frequency doubler with a 6.8 dBm deliverable peak output power and a conversion gain of 11.8 dB. The designed chip is composed of a 28.5 dB gain 6-stages 110 GHz power amplifier, an optimized push-push doubler biased in class-C configuration, and an output impedance matching network. A numerical method had been applied here for designing each implemented matching network achieving the optimum matching while maintaining the minimum insertion loss as well. The presented design shows the highest output power among the other sub-THz-designed CMOS counterparts. The design occupies an area of 0.795 mm² and shows a total DC power dissipation of 262 mW and DC-RF efficiency of 1.87%.

最佳匹配 189-232 GHz 6.8 dBm 输出功率 CMOS 倍频器

本文介绍了一款 215-252 GHz 40 nm 块状 CMOS 倍频器的设计和测量结果，该倍频器的峰值输出功率为 6.8 dBm，转换增益为 11.8 dB。所设计的芯片由一个增益为 28.5 dB 的 6 级 110 GHz 功率放大器、一个偏置为 C 类配置的优化推推倍频器和一个输出阻抗匹配网络组成。在设计每个已实现的匹配网络时，都采用了数值方法，以实现最佳匹配，同时保持最小插入损耗。在其他亚千赫设计的 CMOS 同类产品中，本设计的输出功率最高。该设计所占面积为 0.795 mm2，总直流耗散功率为 262 mW，直流射频效率为 1.87%。

期刊介绍： International Journal of RF and Microwave Computer-Aided Engineering provides a common forum for the dissemination of research and development results in the areas of computer-aided design and engineering of RF, microwave, and millimeter-wave components, circuits, subsystems, and antennas. The journal is intended to be a single source of valuable information for all engineers and technicians, RF/microwave/mm-wave CAD tool vendors, researchers in industry, government and academia, professors and students, and systems engineers involved in RF/microwave/mm-wave technology. Multidisciplinary in scope, the journal publishes peer-reviewed articles and short papers on topics that include, but are not limited to. . . -Computer-Aided Modeling -Computer-Aided Analysis -Computer-Aided Optimization -Software and Manufacturing Techniques -Computer-Aided Measurements -Measurements Interfaced with CAD Systems In addition, the scope of the journal includes features such as software reviews, RF/microwave/mm-wave CAD related news, including brief reviews of CAD papers published elsewhere and a "Letters to the Editor" section.
