Abstract :
Ultra-Wideband (UWB) is an emerging new technology for wireless personal area networks (WPAN) and is based on IEEE 802.153a standard. The frequency range of operation is between 3.1-10.6 GHz, which is divided into several band groups. The LNA in our paper is operable at the first band group of UWB that is 3.1-4.8 GHz range. The LNA is designed and laid out in a 0.18 mum CMOS process and with 1.8-V power supply. Simulation shows the LNA achieves 2-GHz bandwidth with minimum gain variation, two voltage gain modes of 20dB and 15dB respectively and noise figure around 5.2dB, while draws 15 mA current
