摘要

本文设计的LNA具有良好的信噪比、高而平坦的功率增益、良好的输入阻抗匹配和良好的相位线性，可放大UWB频段(3.1-10.6 GHz)内接收的无线电信号。采用0.4 μm CMOS工艺实现。对LNA进行了详细的设计，并在ADS上进行了仿真。仿真结果表明，LNA的增益在目标频带内是平坦的，约为12 dB。所设计的LNA噪声系数良好，在3.35 ~ 2.8 dB范围内。最重要的成就是由群延迟决定的线性度，该实现实现了±12.175 ps范围内的群延迟变化。

A low-noise amplifier design for 3.1–10.6 GHz impulse radio ultra wideband receivers

In this paper the LNA is designed to amplify the radio-signals received in the UWB band (3.1-10.6 GHz) with a good signal-to-noise ratio property, high and flat power gain, good input impedance matching and good phase linearity. The 0.4 μm CMOS technology is used for implementation. A detailed designed is carried for the LNA and is simulated on ADS. The simulation results demonstrate that the gain is flat over the band of interest and is of the order of 12 dB. The noise figure of the designed LNA is good and is in the range of 3.35 to 2.8 dB. The most important achievement is the linearity which is decided by group delay and this implementation achieves group delay variations in the range of ± 12.175 ps.
