This manuscript presents the low noise amplifier design and performance analysis of receiver RF front-end for narrowband wireless communications. The LNA is a central building block of the wireless receiver. A single-ended cascode CMOS LNA is purposeful for reconfigurable applications such as Wireless LAN. The scope of this manuscript is to design an LNA appropriate for wireless applications with improved performance metrics. The contributions of this paper are noise reduction and high gain using an inductive degeneration common source stage. The proposed LNA espouses the entire simulation results in the frequency band of 2.44GHz. The excellent Noise Figure obtained as 0.95dB; the preferable power gain (S 21 ) is 17dB, also the results of P-1dB of -17.3dBm, IIP 3 of -10.7dBm at 2.44GHz, respectively. However, the perfect input and output matching network is achieved with proper reverse shielding and excellent stability.
