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 m...
