摘要

提出了一种用于有线电视接收的宽带低噪声放大器。该放大器使用的拓扑结构不同于通常的放大器，并导致高度线性的LNA。它采用台积电65纳米CMOS技术制造。在2.3 V电源电压下，测量结果显示噪声系数(NF)为5.7 dB, IIP3为+64 dBmV, IIP2为+80 dBmV，功耗为65 mW。增益变化从3db到15db与3db步进。

Wide-band variable-gain LNA in 65 nm CMOS with inverter based amplifier for multi-tuners cable TV reception

This paper presents a wide band Low Noise Amplifier (LNA) intended for cable TV reception. The topology used for this amplifier differs from usual ones, and leads to a highly linear LNA. It was built in TSMC 65-nm CMOS technology. The measurements with 2.3 V supply voltage show 5.7 dB Noise Figure (NF), +64 dBmV IIP3, +80 dBmV IIP2 with 65 mW power consumption. The gain varies from 3 dB to 15 dB with 3 dB steps.
