چکیده
In this paper, a two-stage 0.18 μm CMOS power amplifier (PA) for ultra-wideband (UWB) 3 to 5 GHz based on common source inductive degeneration with an auxiliary is proposed. proposal, used place the 2nd harmonic in core amplified order make up gain progression phenomena at main output node. Simulation results show of 16 dB flatness 0.4 and input 1 compression about -5 dBm from using 1.8 V supply consuming 25 mW. Power added efficiency (PAE) around 47% 4 50 Ω load impedance was also observed.
