Abstract :
An 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-mum 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 mW from a 1.8-V supply and occupies an area of only 0.59 mm2
