The research offers the design of a highly efficient (3.1 -10.6) GHz ultra wide band (UWB) power amplifier (PA) with an improvement in the input matching, using the process of CMOS TSMC 0.065 µm. A wide input matching topology and a resistor-capacitor (RC) interstage are adopted for input matching and flatten gain improvements, respectively. The feedback circuit leading the gate inductor combined with the peaking inductive divider accomplishes a low input return loss and extends the band of operation. The post-layout simulations indicate a high flattened average power gain (S21) of 22.2 ± 1.5 dB while the improved matching topology attains a good input (S11) and output (S22) return loss below -11 dB. Moreover, a small group delay (GD) variation of ± 47.5 ps is achieved for the UWB frequencies. In addition, a great power-added efficiency (PAE) of 33% and an output power () of 11 dBm are achieved. The complete UWB PA design consumes only 19 mW from 1.2 supply voltage.
