摘要：
A 3.1-10.6 GHz ultra-wideband (UWB) low noise amplifier (LNA) utilizing a current-reused technique and a simple high-pass input matching network is proposed. The implemented LNA presents a maximum power gain of 16 dB, and a good input matching of 50 Omega in the required band. An excellent noise figure (NF) of 3.1-6 dB was obtained in the frequency range of 3.1-10.6 GHz with a power dissipation of 11.9 mW under a 1.8-V power supply. The proposed UWB LNA demonstrates the highest power gain and lowest NF among the published works in 0.18-mu m CMOS technology.
