摘要

一种用于正交压控振荡器的相位降噪技术可降低并形成注入系统的晶体管热噪声，并提供相幅噪声转换机制以进一步降低相位噪声。两种实验设计分别提供以5.1GHz和5.3GHz为中心的17%和1%调谐范围，在1MHz偏移时相位噪声分别为-132.6dBc/Hz和-134.4dBc/Hz

A phase-noise reduction technique for quadrature LC-VCO with phase-to-amplitude noise conversion

A phase-noise reduction technique for quadrature VCOs reduces and shapes the transistor thermal noise injected into the system, and also provides a phase-to-amplitude noise conversion mechanism to further reduce phase noise. Two experimental designs provide 17% and 1% tuning ranges centered at 5.1GHz and 5.3GHz with phase noise of -132.6dBc/Hz and -134.4dBc/Hz at a 1MHz offset, respectively
