In this paper, an Ultra Wideband (UWB) Low Noise Amplifier for 3.1-10.6 GHz is designed and simulated. The proposed LNA uses resistive shunt feedback techniqueand an inter stage inductor as an inductive peaking to realize the flat gain throughout the UWB band. The designed UWB LNA has a noise figure of 2.7dB, 17dB flat gain in the frequency range of 3.1-10.6 GHz. And input impedance matching parameter, S11, is lower than -10dB over bandwidthfrequency range. It consumes 26mW from a supply voltage of 1.5 V.
