摘要

提出了一种新的基于变压器的低噪声放大器拓扑结构。该结构通过闭合在公共栅极级附近的电流对电流正反馈实现了低噪声输入匹配和大于1的电流增益。该放大器插入一个高线性电流模式射频前端接收器，工作在4.15-4.4GHz之间，NF为4.2dB，增益为24.2dB, IIP3为-2dBm

Common Gate Transformer Feedback LNA in a High IIP3 Current Mode RF CMOS Front-End

A new topology of transformer based low noise amplifier is presented. The structure realizes a low noise input match and a current gain greater than one by a current to current positive feedback closed around a common gate stage. The amplifier is inserted in a high linearity current mode RF front-end receiver working between 4.15-4.4GHz with a NF of 4.2dB, a gain of 24.2dB and an IIP3 of -2dBm
