Abstract :
This paper presents a design technique for a low-noise amplifier for the 1.8–4 GHz ultra wideband (UWB) wireless receivers. The LNA uses a circuit topology consisting of one gain stage with series inductor feedback using ATF technology and it is operated at 1 V. The noise figure of this LNA varies from 3 to 1.5 dB, and its gain is very flat 10 dB throughout frequency band spanning from 1.8 to 4 GHz. These results were obtained using Agilent ADS commercial simulator and confirmed with Ansoft designer utilizing ATF-10136 amplifier technology.
