A 98.4fs-Jitter 12.9-to-15.1GHz PLL-Based LO Phase-Shifting System with Digital Background Phase-Offset Correction for Integrated Phased Arrays

📋 论文概要

该论文提出了一种基于锁相环的本地振荡器移相系统，通过数字后台相位偏移校正技术，在12.9至15.1GHz频率范围内实现了98.4fs的抖动性能，解决了5G毫米波通信中对超低抖动和精确波束控制的需求。

💡 主要创新点

• 提出了一种数字后台相位偏移校正技术，无需模拟校准即可实现高精度相位控制。
• 采用基于锁相环的移相架构，在宽频率范围内实现了超低抖动性能。

In regard to jitter, digital bang-bang phase-locked loops (BBPLLs) have been recently shown as capable of satisfying the very stringent requirements, while at the same time occupying less area than their analog counterparts [3]. This makes them particularly well-suited to the socalled localized LO-generation approach, where a synthesizer is placed in each of the
