摘要

本文提出了一种采用消噪结构的宽带LNA。它涵盖了从500千赫到1.4千兆赫的频段。为了使这种结构更节能，采用了推挽技术。仿真结果表明，该方法的最小噪声系数(NF)为1.75dB。推拉技术降低了功耗和模具面积。它从1.8V电压电源中吸取12 mA电流，核心面积为0.11 mm2。

A 500 kHz-1.4 GHz push-pull differential noise cancellation LNA

This paper presents a wideband LNA that employs a noise cancellation structure. It covers the frequency band from 500 kHz to 1.4 GHz. To make this structure more power efficient, a push-pull technique is exploited. Simulation results show that a minimum noise figure (NF) of 1.75dB is achieved. The push-pull technique reduces the power consumption and die area. It draws 12 mA current from 1.8V voltage supply with a core area of 0.11 mm2.
