Abstract

A novel active-inductor based VCO design, employing a 180 nm TSMC technology, is postulated in this work. The coarse frequency is obtained in this VCO system by regulating the MOS-based active inductor. This design provides a high oscillation frequency of 3.7 GHz and a tuning range of 99.25% when the voltage ranges from 1 to 2 V. The total power consumed by this active-inductor based VCO varies from 0.7 mW to 33.32 mW within the specified range. The achieved phase noise is − 107 dBc/Hz at 1 MHz offset frequency. The figure of merit measured is − 162.15 dBc/Hz. The results demonstrate that the proposed VCO functions more effectively than the existing VCOs.

设计和分析基于有源电感器的低相位噪声、宽可调 CMOS 低功率 VCO

本研究提出了一种基于有源电感器的新型 VCO 设计，采用了 180 纳米 TSMC 技术。该 VCO 系统通过调节基于 MOS 的有源电感器获得粗频率。该设计的振荡频率高达 3.7 GHz，当电压范围在 1 至 2 V 之间时，调谐范围可达 99.25%。在指定范围内，这种基于有源电感的 VCO 消耗的总功率从 0.7 mW 到 33.32 mW 不等。在 1 MHz 偏移频率下，相位噪声为 - 107 dBc/Hz。测得的优越性为 - 162.15 dBc/Hz。结果表明，拟议的 VCO 比现有的 VCO 更有效。
