摘要

四阶滤波器采用了一种不滤波所需信号而抑制干扰的方法，放松了噪声、线性度和功耗之间的权衡。该滤波器专为2.4 GHz接收器基带设计，采用0.25 /spl mu/m CMOS技术制造，其输入参考噪声为17 nV//spl径向/(Hz)，而2.5 V电源的功耗为2 mW，接收器的噪声系数为6 dB，功耗为17.5 mW。

A noninvasive channel-select filter for a CMOS Bluetooth receiver

A fourth-order filter incorporates a method of suppressing interferers without filtering the desired signal, relaxing the trade-offs between noise, linearity, and power dissipation. Designed for the baseband of a 2.4 GHz receiver and fabricated in a 0.25 /spl mu/m CMOS technology, the filter exhibits an input-referred noise of 17 nV//spl radic/(Hz) while dissipating 2 mW from a 2.5 V supply and the receiver achieves a noise figure of 6 dB with a power consumption of 17.5 mW.
