摘要

本文提出了一种具有宽调谐范围的源前馈环形压控振荡器（SFRVCO）的单事件瞬态（SET）容错锁相环（PLL），适用于串行快速输入/输出（SRIO）。脉冲灵敏度函数（ISF）分析表明，在具有高电源抑制比（PSRR）的可调电流源控制下，所提出的振荡器具有更低的相位噪声，其调谐范围达到 0.9-6.6 GHz，同时还具有更好的 SET 容差。所提出的 SFRVCO 采用 28 纳米 CMOS 工艺实现，在与 2.5 GHz 载波偏移 1-MHz 时，相位噪声为 -96.7 dBc/Hz，核心面积为 0.0008 mm2。激光实验表明，辐照阈值为 600 pJ。

A Wide-Tuning PLL With SET-Tolerant Quadrature Ring VCO for Serial Rapid I/O

This article presents a single-event transient (SET) tolerant phase-locked loops (PLLs) with a wide-tuning-range source-feedforward ring voltage-controlled oscillator (SFRVCO), suitable for serial rapid I/O (SRIO). The analysis of impulse sensitivity function (ISF) shows that the proposed oscillator has lower phase noise, and its tuning range reaches 0.9–6.6 GHz under the control of adjustable current source with high power supply rejection ratio (PSRR), which also exhibits better SET tolerance. Implemented in a 28-nm CMOS process, the proposed SFRVCO achieves a phase noise of −96.7 dBc/Hz at 1-MHz offset from a 2.5-GHz carrier, occupying a core area of 0.0008 mm2. Laser experiments indicate an irradiation threshold of 600 pJ.

期刊介绍： The IEEE Transactions on Nuclear Science is a publication of the IEEE Nuclear and Plasma Sciences Society. It is viewed as the primary source of technical information in many of the areas it covers. As judged by JCR impact factor, TNS consistently ranks in the top five journals in the category of Nuclear Science & Technology. It has one of the higher immediacy indices, indicating that the information it publishes is viewed as timely, and has a relatively long citation half-life, indicating that the published information also is viewed as valuable for a number of years. The IEEE Transactions on Nuclear Science is published bimonthly. Its scope includes all aspects of the theory and application of nuclear science and engineering. It focuses on instrumentation for the detection and measurement of ionizing radiation; particle accelerators and their controls; nuclear medicine and its application; effects of radiation on materials, components, and systems; reactor instrumentation and controls; and measurement of radiation in space.
