1一种新型的5GHz自适应偏置及可变增益低噪声放大器显示文摘该文提出了一种新型的自适应偏置及可变增益低噪声放大器(LNA),利用电荷泵(亦称电压倍增器)将LNA输出信号转换成与LNA射频输入信号功率成比例变化的直流信号,以此信号同时反馈控制LNA的偏置和增益,来实现自适应偏置以及可变增益低噪声放大器,从而极大地改善了LNA的输入线性范围。鉴于5GHz频率下,Bipolar相对于CMOS更好的频率特性和低噪声特性,该项研究采用了BiCMOS工艺,实现了低于3.0dB的噪声系数(高增益状态下)和大约13dBm的输入三阶交调点IIP3的控制范围以及大于15dB的增益控制范围。徐化 姚远 石寅 Fa Foster Dai 2006电子与信息学报2006,28,8:1
