基于磁耦合谐振器的低噪声正交VCO，支持毫米波无线片上处理
56–60.4GHz可调频率，1MHz偏移相位噪声<-95dBc/Hz，1.5°相位误差，22mA@1V
毫米波正交VCO磁耦合谐振器CMOS低相位噪声
▸创新点1：磁耦合谐振器实现低噪声正交振荡。该方法通过两个调谐VCO环形结构，利用级间无源元件控制振荡频率，显著降低了相位噪声，并实现了精确的正交相位输出，相位噪声优于-95 dBc/Hz @ 1-MHz偏移。
▸创新点2：宽频带可编程分频器设计。该电路采用时钟差分放大器作为动态CML锁存器，实现了20至70 GHz的宽频带可编程分频，功耗仅为6.5 mW，显著提升了分频器的频率范围和能效。
▸创新点3：动态CML锁存器提升分频器速度与能效。通过动态CML锁存器设计，分频器在高速运行的同时保持了低功耗，实现了高速度与低功耗的平衡，适用于毫米波频段的应用。

conversion architectures and simplifying phased-array systems,
frequency division with an operating range wide enough to com-
pensate spreads due to component variations. This paper addresses
