Objectives: To design a Low Noise Amplifier (LNA) using Double Gate (DG) FinFET with 1.2 dB noise figure over bandwidth of 24GHz. Methods: Temperature effect on noise figure, stability is also analyzed and the effect of thermal noise and flicker noise in CG LNA is presented. Findings: The designed LNA gives an IIP3 value of 5.58 dB and 1dB compression point of -5.6 dB with proper matching conditions. The maximal efficiency of 80% was achieved for different topologies with 364 MHz switching frequency. Improvements: The designed amplifier provides a maximum voltage gain of 17 dB with a noise figure less than 2 dB as compared to that of conventional MOSFETs based LNA.
