摘要
由于超宽带技术能够在短距离内传输几百兆的数据,帮助人们摆脱对导线的依赖,因此使得大带宽数据的无线传输从几乎不可能变为现实。尽管目前超宽带技术的标准还没有统一,但是低噪声放大器终归是其接收机中一个不可或缺的重要模块。文章介绍了一种基于0.18μmCMOS工艺、适用于超宽带无线通信系统接收前端的低噪声放大器。结合计算机辅助设计,该超宽带低噪声放大器输入、输出均实现良好的阻抗匹配,在3GHz～10GHz的频带范围内实现了增益G=29±1dB,噪声系数小于4dB。在1.8V工作电压下放大器的直流功耗约为35mW。
As UWB technology transfer within a short distance a few megabytes of data,to help people get rid of dependence on the wire,thus making big-bandwidth wireless data transmission from the almost impossible into reality.Although UWB standard has not yet unified,but,after all,is its low-noise amplifier in a receiver indispensable module.This paper describes a technique based on 0.18μm CMOS for UWB wireless communication system receiver front-end low-noise amplifier.Combined with computer-aided design,the ultra-wideband low noise amplifier input and output are to achieve good impedance matching,in the 3 GHz ～10GHz frequency range to achieve a gain G = 29 ± 1dB,noise figure less than 4dB for.1.8V operating voltage in the DC power amplifier is about 35mW.
