摘要

本文提出了一种新型的宽带、无电感、电阻反馈的CMOS LNA。该放大器设计用于0.3 GHz- 2ghz频段。所实现的LNA在1ghz时的测量电压增益为12db, 3db带宽为2ghz。在900 MHz时测量到IIP3为-16 dBm，噪声系数为4 dB。IIP2的测量值为- 13dbm。在300mhz ~ 1ghz频段内，Sll优于- 10db。1.2 V电源的功耗为18mw。该电路采用数字CMOS 90纳米低功耗(LP)工艺设计，没有额外的工艺选项。

A broadband, inductorless LNA for multi-standard aplications

In this paper a novel broadband, inductor-less, resistive-feedback, CMOS LNA is presented. The amplifier is designed for the frequency band 0.3 GHz-2 GHz. The measured voltage gain of the implemented LNA is 12 dB at 1 GHz and the 3 dB bandwidth is 2 GHz. An IIP3 of -16 dBm and a noise figure of 4 dB are measured at 900 MHz. The value of the measured IIP2 is -13 dBm. The Sll is better than -10 dB in the frequency band from 300 MHz up to 1 GHz. The power dissipation is 18 mW from a 1.2 V supply. The circuit is designed in a digital CMOS 90 nm low power (LP) process without extra process options.
