摘要

本文提出了基于可调谐有源电感(TAI)的振荡器拓扑结构。本文报道的TAI振荡器电路采用动态相位注入和前馈机制来改善相位噪声性能和动态范围。在载波频率为11.8 GHz的1MHz偏置、200mhz调谐和3V, 30ma直流偏置下,测量的相位噪声优于- 110dBc/Hz。

Tunable active inductor oscillator
In this paper tunable active inductor (TAI) based oscillator topologies are presented. The reported TAI oscillator circuit uses dynamic phase-injection and feed-forward mechanism for improving the phase noise performance and dynamic ranges. The measured phase noise for carrier frequency 11.8 GHz is better than −110dBc/Hz at 1MHz offset with 200 MHz tuning and DC bias of 3V, 30 mA.
