In this paper, a 2.8-10.6GHz low-noise amplifier for ultra-wideband applications is presented. The proposed UWB-LNA uses inter-stage technique (current reuse topologywith a peaking inductor) to achieve low power consumption. It is designed using TSMC 0.18  m CMOS technology. Simulationresults show the LNA achieves flat S21 of 12.32 ± 1.07 dB, S11 below -7.45 dB, S22 below -8.45 dB, S12 below -47 dB and flat NFof 3.2 ± 0.2 dB over the 2.8-10.6-GHz band of interest, with onlypower consumption of 5.74mW.
