超宽带（UWB）是一种新兴的无线个域网（WPAN）技术，基于IEEE 802.153a标准。工作频率范围在3.1-10.6 GHz之间，分为几个频段组。本文设计的低噪声放大器可工作在UWB的第一频段，即3.1-4.8 GHz。LNA的设计和布局在一个0.18妈妈CMOS工艺和1.8 V电源。仿真结果表明，该低噪声放大器的带宽为2GHz，增益变化最小，两种电压增益模式分别为20 dB和15 dB，噪声系数约为5.2dB，功耗为15 mA
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
