چکیده
ETRI Journal, Volume 29, Number 5, October 2007 ABSTRACT⎯An ultra-wideband low-noise amplifier is proposed with operation up to 8.2 GHz. The amplifier is fabricated with a 0.18-μm CMOS process and adopts a twostage cascode architecture and a simplified Chebyshev filter for high gain, wide band, input-impedance matching, and low noise. The gain of 19.2 dB and minimum noise figure of 3.3 dB are measured over 3.4 to 8.2 GHz while consuming 17.3 mW of power. The Proposed UWB LNA achieves a measured power-gain bandwidth product of 399.4 GHz.

Ultra wideband (UWB) radio communication is capable of a high data rate with low radiated power. A key issue for UWB design is LNA input/output matching over a wide bandwidth: 3 to 5GHz for the lower band and 3 to 10GHz for the entire band. Several UWB LNAs have been proposed in recent years. The UWB CMOS LNA presented in [1] employs a Chebyshev filter for input matching and a source follower f...
