Chih-Fan LiaoSHEN-IUAN LIU2018-09-102018-09-102007-0200189200http://scholars.lib.ntu.edu.tw/handle/123456789/333712An ultra-wideband 3.1-10.6-GHz low-noise amplifier employing a broadband noise-canceling technique is presented. By using the proposed circuit and design methodology, the noise from the matching device is greatly suppressed over the desired UWB band, while the noise from other devices performing noise cancellation is minimized by the systematic approach. Fabricated in a 0.18-μm CMOS process, the IC prototype achieves a power gain of 9.7 dB over a -3 dB bandwidth of 1.2-11.9-GHz and a noise figure of 4.5-5.1 dB in the entire UWB band. It consumes 20 m W from a 1.8-V supply and occupies an area of only 0.59 mm2. © 2007 IEEE.Broadband; Low-noise amplifier (LNA); Noise canceling; Ultra-wideband (UWB)Noise canceling; Ultra-wideband (UWB); Bandwidth; CMOS integrated circuits; Low noise amplifiers; Noise abatement; Signal receivers; Broadband networksjournal article10.1109/JSSC.2006.8893562-s2.0-33847713789WOS:000243915300009
