摘要

提出了一种宽范围可调谐CMOS压控振荡器(VCO)。VCO采用片上可变电感和开关电容作为可变元件。该VCO采用标准的0.18 μ m CMOS工艺制作，有五层金属层。振荡频率可从1.28 GHz调谐到2.75 GHz，调谐范围为72%。

A Wideband CMOS LC-VCO Using Variable Inductor

This paper proposes a wide-range tunable CMOS voltage controlled oscillator (VCO). VCO uses an on-chip variable inductor and switched capacitors as variable elements. The VCO was fabricated using a standard 0.18 mum CMOS process with five metal layers. The oscillation frequency can be tuned from 1.28 GHz to 2.75 GHz with tuning range of 72 %.
