This paper proposes a novel low-power fully-differential ultra-wideband (UWB) low noise amplifier (LNA) for 6-9-GHz UWB receivers in digital 90nm CMOS. The capacitive cross-coupled common-gate (CG) stage is cascaded with a cross-coupled common-source (CS) second stage to perform the wideband input impedance matching, low noise figure (NF), low power, and flat-high-wideband gain which is due to the stagger tuning amplification. The DC power consumption is further reduced by the current-reuse topology. The simulation results achieve the minimum NF of 2.55dB, maximum voltage gain of 24.8dB with 3-dB bandwidth of 6-9-GHz, and IIP3 of 3.57dBm at 9GHz. The return loss is less than -12dB in the desired band because of the CG stage as the input stage. The proposed UWB LNA consumes 2.3mW core DC power at 1V supply voltage.
