Abstract

A low-noise amplifier employing transformer feedback for 5-6 GHz WLAN applications operates from a 1 V supply and achieves a measured gain of 14.2 dB, noise figure (NF) of 0.9 dB, and IIP3 of +0.9 dBm, while consuming 16 mW. We benchmark the feedback design to a cascode topology fabricated in the same technology that realizes 14.1 dB gain, 1.8 dB NF, and IIP3 of +4.2 dBm while dissipating 21.6 mW at 1.8 V. Both designs are fully-differential and are implemented in 0.18 /spl mu/m CMOS.

用于5-6 GHz WLAN的1 V 0.9 dB NF低噪声放大器，采用0.18 /spl mu/m CMOS

采用变压器反馈的低噪声放大器适用于5-6 GHz WLAN应用，工作电源为1 V，测量增益为14.2 dB，噪声系数(NF)为0.9 dB, IIP3为+0.9 dBm，功耗为16 mW。我们将反馈设计基准测试到采用相同技术制造的级联码拓扑，该拓扑实现14.1 dB增益，1.8 dB NF和+4.2 dBm的IIP3，同时在1.8 V下功耗为21.6 mW。这两种设计都是全差分的，并在0.18 /spl mu/m CMOS中实现。
