摘要

为了实现超宽带压控振荡器，提出了一种基于开关电感的新型谐振器。该VCO采用0.13 μ m CMOS设计和制造，并在晶圆上进行了全面评估。测量结果表明，该VCO在1.81 GHz ~ 4.63 GHz范围内具有高达87.6%的调谐率。在1.81 GHz载波的1mhz偏移处，测量得到- 124.4 dBc/Hz的相位噪声1。

A switched-inductor based VCO with an ultra-wideband tuning range of 87.6 %

A novel switched-inductor based resonator is proposed to implement an ultra-wideband VCO. The VCO is designed and fabricated using 0.13 µm CMOS and fully evaluated on wafer. The measured results show that the proposed VCO has a tuning range as high as 87.6% spanning from 1.81 GHz to 4.63 GHz. The measured phase noise of −124.4 dBc/Hz at 1 MHz offset from the 1.81 GHz carrier is obtained 1.
