摘要
本文介绍了基于噪声优化技术设计的低噪声放大器的最小噪声系数的变化。结果表明，LNA的最小噪声系数不随Lg的变化而变化。为了验证效果，采用CMOS 0.13 mum技术设计了一个1.575 GHz、0.55 dB噪声系数的LNA。LNA由1.1 V电源供电，增益12.9 dB，在很宽的频率范围内保持稳定。的。LNA仅吸收1 mA，输入回波损耗为-17 dB
Minimum noise figure of a low noise amplifier based on noise optimization technique
This paper describes changes of the minimum noise figure of a low noise amplifier designed based on a noise optimization technique. We show that the minimum noise figure of the LNA does not change with changes in Lg. To verify the effects a 1.575 GHz, 0.55 dB noise figure LNA was designed in CMOS 0.13 mum technology. Powered by a 1.1 V supply the LNA features 12.9 dB of gain and is stable over a wide frequency range. The. LNA draws only 1 mA and has an input return loss of -17 dB
