Abstract :
This paper presents the design of power amplifier (PA) 0.18 um CMOS technology for ultra wide band (UWB) application at 3.1-10.6 GHz. This PA design is based on two-stage common source topology with resistive shunt feedback technique and output buffer to achieve flat and higher gain, wider bandwidth and better stability. The simulation results show that the average power gain of 12.4 ± 1.1 dB, input return loss (S11) and output return loss (S22) less than -8.6 dB is achieved. Furthermore, low power consumption is 19 mW from 1.0 V supply voltage.
