In this paper, we proposed a low noise amplifier (LNA) for ultra wideband (UWB) application using TSMC 0.18μm CMOS technology. To satisfy the wide input matching, LC high-pass filter matching network is utilized in the first stage. To obtain the low power characteristic, folded-cascode with current reused technique is utilized in the second stage. The designed UWB LNA has the voltage gain of 17.6 ∼ 19.7 dB and the noise figure of 1.8∼2.2 dB over the frequency band of interest (3.1-10.6 GHz). The total power consumption of the UWB LNA is 4.0 mW (core 2.93 mW) from 1 V supply voltage.
