摘要

1.8 GHz正交压控振荡器采用标准的0.35 /spl mu/m CMOS，具有三层金属层，在18%的调谐范围内显示-140 dBc/Hz或更低的相位噪声，同时从2v电源获取25 mA。压控振荡器输出之间的正交相位误差最多为0.25/spl度/。

A low-phase-noise low-phase-error 1.8 GHz quadrature CMOS VCO

A 1.8 GHz quadrature VCO in standard 0.35 /spl mu/m CMOS with three metal layers shows -140 dBc/Hz or less phase noise across an 18% tuning range, while drawing 25 mA from a 2 V power supply. The quadrature phase error between the VCO outputs is at most 0.25/spl deg/.
