Analysis and design of transformer-based CMOS ultra-wideband millimeter-wave circuits for wireless applications
Abstract: With a lot of millimeter-wave (mm-Wave) applications being issued, wideband circuits and systems have attracted much attention because of their strong applicability and versatility. In this paper, four transformer-based ultra-wideband mm-Wave circuits demonstrated in CMOS technologies are reviewed from theoretical analysis, implementation, to performance. First, we introduce a mm-Wave low-noise amplifier with transformer-based Gm-boosting and pole-tuning techniques. It achieves wide operating bandwidth, low noise figure, and good gain performance. Second, we review an injection-current-boosting technique which can significantly increase the locking range of mm-Wave injection-locked frequency triplers. Based on the injection locked principle, we also discuss an ultra-wideband mm-Wave divider with the transformer-based high-order resonator. Finally, an E-band up-conversion mixer is presented; using the two-path transconductance stage and transformer-based load, it obtains good linearity and a large operating band.

摘要：近年来，由于大量毫米波无线应用的产生，具有更强通用性的宽带毫米波电路和系统引起广泛关注。总结了4种基于片上变压器结构超宽带毫米波电路的理论分析、设计方法和综合性能。其一为毫米波低噪声放大器，采用基于变压器的跨导增强和极点调谐技术；通过采用这两种技术，该电路同时实现了较大工作带宽、低噪声系数和良好功率增益。其二为毫米波注入锁定三倍频器，采用注入电流增强技术，有效拓展了倍频器的锁定带宽。进一步，采用类似注入锁定技术结合变压器高阶谐振腔方案，实现了一款超宽带毫米波注入锁定分频器。最后，介绍了一款E波段上混频器，其采用两路跨导并联结构和基于变压器的多极点负载，实现了优异线性度和较大工作带宽。
