Low noise amplifier is the foremost, challenging and indispensable building block to build a receiver. The current reuse technique is addressed to optimize noise performance and power efficiency while maintaining a good power gain and input/output matching. The LNA was designed and implemented using IBM 0.13μm CMOS technology. Simulation results show a power gain (S21) of 12.5dB, a good noise figure (NF) of 3.05dB and an input return loss (S11) of less than -16.5dB. The LNA occupies an area of 0.11mm2 and consumes 11.08mW of power for the 1.4V power supply. Thus this LNA should be readily useful for ultra-wideand receiver systems. __________________________________________________________________________________________
