摘要

采用标准的0.18 μ m CMOS技术演示了40 ghz宽带压控振荡器。为了在毫米波频率下实现宽调谐范围，提出了一种切换传输线结构的非均匀驻波压控振荡器。通过切换传输线的长度，40 GHz VCO设计的频率调谐范围可达7.5 GHz，同时在1 mhz偏移时保持优于-96 dBc/Hz的相位噪声

A 40-GHz Wide-Tuning-Range VCO in 0.18-~m CMOS

A 40-GHz wideband VCO is demonstrated in a standard 0.18-mum CMOS technology. In order to achieve wide tuning range at millimeter-wave frequencies, a non-uniform standing-wave VCO with a switched-transmission line architecture is proposed. By switching the length of the transmission line, a frequency tuning range of 7.5 GHz is achieved for the 40-GHz VCO design while maintaining a phase noise better than -96 dBc/Hz at 1-MHz offset
