A 2.8-10.6GHz Low-Power Low-Noise Amplifier for Ultra-Wideband Recivers

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 topology with a peaking inductor) to achieve low power consumption. It is designed using TSMC 0.18 μm CMOS technology. Simulation results 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 NF of 3.2 ± 0.2 dB over the 2.8-10.6-GHz band of interest, with only power consumption of 5.74mW.
