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 through out 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.
