In this paper, we introduce a systematic method to design CMOS low noise amplifier (LNA) for ultrawideband (UWB) applications. The proposed method is addressed to optimize noise performance and power efficiency while maintaining good input and output matching. The synthesized LNA achieves up to 14dB power gain with a low noise figure (NF) of 2dB and provides a reasonably acceptable input and output matching of -10dB across the frequency range of 3~5GHz. The developed LNA, implemented in TSMC
