摘要
设计了一款工作在2.4GHz的可变增益CMOS低噪声放大器,电路采用HJKJ0.18μm CMOS工艺实现。测试结果表明,最高增益为11.5dB,此时电路的噪声系数小于3dB,增益变化范围为0~11.5dB。在1.8V电压下,电路工作电流为3mA。
A 2.4 GHz variable gain CMOS low noise amplifier (LNA) is presented in this paper. This LNA is implemented in HJKJ 0. 18 μm CMOS process and the measurement results show that it achieves less than 3 dB noise figure with 11.5 dB maximum power gain, the variable gain range is 0-11.5 dB. It draws 3 mA current from 1.8 V power supply.
