Abstract :
An ultra-wideband (UWB) noise-canceling low-noise amplifier (LNA) is presented. By using inductive series and shunt peaking techniques, the effective bandwidth of noise canceling is extended. This LNA has been fabricated in a 0.18μm CMOS process. The measured noise figure is 4.5-5.1dB over 3.1-10.6-GHz, while the power gain is 9.7dB with a -3-dB bandwidth of 1.2-11.9-GHz. It consumes 20mW from a 1.8V supply and occupies only 0.59mm2.
