A Cancellation Technique for Reciprocal-Mixing Caused by Phase Noise and Spurs M
一种相位噪声和杂散滤波技术，通过利用相位噪声对称性实现互混噪声消除，显著降低接收机噪声系数。
-15dBm阻塞器下互混噪声降低25dB，功耗8mA
相位噪声互混消除接收机噪声振荡器设计杂散滤波
▸利用相位噪声在载波周围的对称性进行噪声消除
▸通过双倍阻塞器拍频的互混镜像实现带内噪声抵消
▸打破传统振荡器中功率与相位噪声的权衡关系
Abstract
A phase noise and spur filtering technique suppresses
the phase-noise contribution to the receiver noise figure in the pres-
ence of a –15 dBm blocker by 25 dB consuming only 8 mA, bridging
the performance gap between ring o scillators and LC-oscillators.
The technique breaks the conventi onal trade-off between power
and phase-noise in oscillators. It makes use of the symmetry of
phase noise around the carrier by using the image of the recip-
rocal-mixing at double the block er beat frequency to c
