| Abstract: | 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. |
