摘要

通用接收机采用了一种反馈方法来减轻噪声-线性权衡和一种新的谐波抑制(HR)方法，不需要精确的相位匹配。该原型采用28纳米CMOS技术实现，在200 kHz至160 MHz的信道带宽范围内提供射频信道选择滤波，在功率为49 mW时，噪声系数为2.1-4.2 dB, HR > 60.8 dB。

A 0.4-6 GHz Receiver for LTE and WiFi

A universal receiver employs a feedback method to alleviate noise-linearity trade-offs and a new harmonic rejection (HR) method that does not require accurate phase matching. Realized in 28-nm CMOS technology, the prototype provides channel selection filtering at RF for channel bandwidths from 200 kHz to 160 MHz and exhibits a noise figure of 2.1-4.2 dB with HR > 60.8 dB while drawing 49 mW.
