Abstract: An ultra-wideband Low Noise Amplifier (LNA) employing a Common Gate (CG) topology with load network including dual resonance is presented. This LNA has both flat Noise Figure (NF) and wideband input matching in 3.1 GHz-10.6 GHz frequency range applications. The frequency response of common gate-common source cascade topology is improved by adopting inductive series peaking technique. The proposed LNA presents 19.11 dB peak power gain at 9 GHz, 17.94 dB gain for the (4.5-9.5) GHz frequency range and 50 Ohm good enough input matching in the desired band by importing 90 nm CMOS process and model parameters to Advanced Design System (ADS) software. A fine NF less than 2.88 dB is attained in (3.1-10.6) GHz frequency range with 9 mW power dissipation from 1.2 V supply voltage. The input-output reflection coefficients (S11-S22) are -17.61 dB and -6.22 dB at 9 GHz respectively. The reverse isolations (S12) below -50 dB is achieved.
