摘要

采用台积电0.25μm RF CMOS 1P5M工艺设计并制作了双核宽带CMOS LC压控振荡器。通过开关电容阵列和开关变容管阵列的组合，该VCO实现了800MHz至1730MHz的频率调谐范围，控制电压在0.2V-2.2V之间变化，同时保持了小于50MHz/V的调谐灵敏度。当VCO核心从2.5V电源汲取8mA时，测量到的单侧相位噪声为-120dBc/Hz，与1060MHz载波偏移1MHz。

A dual core wideband CMOS LC VCO with low tuning sensitivity

A dual core wideband CMOS LC VCO has been designed and fabricated in TSMC 0.25μm RF CMOS 1P5M process. Using a combination of a switched capacitor array and a switched varactor array, this VCO achieves a frequency tuning rang of 800MHz to 1730MHz with a control voltage varying from 0.2V-2.2V, while maintaining a tuning sensitivity of less than 50MHz/V.The measured single-side phase noise is -120dBc/Hz at a 1MHz offset from a 1060MHz carrier when the VCO core is drawing 8mA from a 2.5V supply.
