📋 论文概要

本文提出了一种基于磁耦合谐振器的毫米波正交压控振荡器（VCO），工作在60GHz频段。该设计旨在为直接转换收发器和相控阵系统提供紧凑、低相位噪声的正交信号参考，同时保持中等功耗。通过磁耦合谐振器实现正交相位生成，有效抑制了相位噪声并减小了芯片面积。

💡 主要创新点

• 提出采用磁耦合谐振器替代传统方法，在毫米波频段实现紧凑型正交VCO结构。
• 通过磁耦合机制优化相位噪声性能，同时降低功耗和面积开销。
• 在60GHz频段实现了低相位噪声与中等功耗的平衡，适用于无线和有线通信系统。

University of Pavia, Pavia, Italy, 2 University of Modena e Reggio Emilia, Modena, Italy, 3 Istituto Universitario di Studi Superiori di Pavia, Pavia, Italy Wireless signal processing at mm-Waves would benefit from the availability of a quadrature signal reference, enabling direct-conversion transceiver architectures and providing phase rotators drivers in phased arrays systems [1]. They are furthermore attractive for clock recovery in ICs for wireline applications. Search of a compact quadrature generator at around 60GHz with low phase noise at moderate power is the topic of this work. Discarding a double-frequency VCO followed by dividers-by-two given the high frequency range of operation, the most suitable topology borrowed by RF solutions is represented by cross-coupled LC voltage-controlled oscillators [2]. However, the oscillation frequency dependence on the biasing current makes it susceptible to phase noise, close-in in particular [3]. At mm-Waves, this is exacerbated by core
