摘要

这项工作打破了正交误差和相位噪声之间的权衡,典型的正交压控振荡器(qvco),利用耦合锁相环的方法。在28纳米块体CMOS技术上实现的原型显示出$0.9^{\circ}$正交误差,并且在与24 GHz载波的10 MHz偏移处具有-134 dBc/Hz的相位噪声。测量的调谐范围为24 ~ 29.2 GHz,功耗为60 mW。

A 24 GHz Quadrature VCO Based on Coupled PLL with -134 dBc/Hz Phase Noise at 10 MHz Offset in 28 nm CMOS
This work breaks the trade-off between quadrature error and phase noise, typical of quadrature voltage-controlled oscillators (QVCOs), by leveraging a coupled PLL approach. Prototypes implemented in a 28 nm bulk CMOS technology show $0.9^{\circ}$ quadrature error, and -134 dBc/Hz phase noise at 10 MHz offset from the 24 GHz carrier. The measured tuning range spans from 24 to 29.2 GHz, while the power consumption is 60 mW.
