摘要

提出了一种完全可合成的注入锁相锁相环，具有双dco频率跟踪。该设计已在55纳米CMOS上制作，并完全通过数字流程实现布局。所提出的锁相环覆盖0.2至1.2 ghz调谐范围，在4.3 mw功耗下实现3.2ps的绝对有效值抖动(从100kHz到100MHz集成)，相应的抖动功率值(FoM)为-224dB，占用的核心面积仅为0.0225 mm2。

A Fully Synthesizable Injection Locked PLL with Dual-DCO Frequency Tracking in 55nm CMOS

This paper presents a fully synthesizable injection locked phase-locked loop (PLL), with a dual-DCO frequency tracking. The design has been fabricated in 55-nm CMOS and the layout is realized completely by digital flows. The proposed PLL covers a 0.2-to-1.2-GHz tuning range, achieving an absolute rms jitter (integrated from 100kHz to 100MHz) of 3.2ps at 4.3-mW power consumption, with a corresponding jitter-power figure of merit (FoM) of -224dB and the occupied core area is only 0.0225 mm2.
