Abstract

This letter introduces a novel phase detector (PD) for suppressing the reference spur in a 40 GHz integer- $N$ phase-locked loop (PLL). Coined as a spur-compensation phase detector (SCPD), the proposed SCPD duplicates itself to an auxiliary path for an edge-combined phase alignment, such that the spurs generated by the two paths mutually compensate for each other, achieving a net effect of spur canceling. Implemented in a 40-nm CMOS technology, the proposed PLL shows less than −71.4-dBc reference spur, −98- and −117-dBc/Hz phase noise at 1- and 10-MHz offset, respectively, and a minimum rms jitter of 114 fs (10 k–100 MHz). It consumes 23.4-mW power from a 1.1-V power supply, leading to a figure of merit (FoM) of −245 dB.

23.4 mW−72 dBc参考杂散40 GHz CMOS PLL，具有杂散补偿相位检测器

本文介绍了一种新型相位检测器（PD），用于抑制40GHz整数$N$锁相环（PLL）中的参考杂散。作为杂散补偿相位检测器（SCPD），所提出的SCPD将自身复制到用于边缘组合相位对准的辅助路径，使得两个路径产生的杂散相互补偿，实现杂散消除的净效果。在40 nm CMOS技术中实现，所提出的PLL在1和10 MHz偏移处分别显示出小于−71.4 dBc的参考杂散、−98和−117 dBc/Hz的相位噪声，最小均方根抖动为114 fs（10 k–100 MHz）。它从1.1V电源消耗23.4-mW的功率，导致−245 dB的品质因数（FoM）。

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.
