• 論文の詳細を見る

• 2-stage 24GHz low noise amplifier (LNA) was designed using 65nm RF CMOS technology. Since conventional topology with inductive source degeneration provides lower signal gain at 24GHz, a source inductor is eliminated and therefore, modified structure in which a shunt inductor was used for input matching is adopted. Figure of merit (FoM) which includes gain, noise figure, and power consumption was used as a design criterion and was maximized considering various circuit parameters such as transistor channel width of each stage, inductor structure and gate bias voltages. Also, the effect of inter-stage impedance on FoM was analyzed. And for noise simulation, accurate channel thermal noise model was used. Through these steps, FoM of 2-stage LNA was optimized.
