This paper present a new low voltage ultra low power 3 to 5 GHz UWB LNA utilizing a current reuse technique with a simple high pass filter input matching network is proposed . The noise, gain and power performance is improved using inter stage network.The broad band matching , the flat gain and the minimal Noise Figure (NF) are three important factors for the broadband circuits. The implemented 0.18-μm CMOS LNA achieve -8.6 dB input return loss . It performs a 14.1dB maximum gain and a 2.75dB NFmin. Total Power consumption is only 2mW from a 0.9v supply voltage.The power consumption figure of merit(FoM1) and the tuning-range figure of merit(FoM2) are optimal at 7.05dB/mw and 1498 (v.w)-1 , respectively.Compared with previously published UWB LNA, the proposed LNA has smallest supply voltage of 0.9v and ultra low power.
