A 15.1 dB gain, 2.1 dB noise figure (min.), low-noise amplifier (LNA) fabricated in 0.13 mum CMOS covers the entire 3.1-10.6 GHz ultrawideband (UWB). Noise figure variation across this band is limited to plusmn0.43 dB. Reactive feedback reduces the noise figure, stabilizes the gain, and sets the terminal impedances over the prescribed bandwidth. Bias current re-use limits power consumption of the 0.87mm2 IC to 9 mW from a 1.2 V supply
