| 摘 要： | 研究应用于超宽带无线通信系统中的宽带分布式放大器设计方法. 采用电感替代传输线对晶体管寄生电容进行补偿的方法实现带宽拓展. 分布式放大器既能扩大其带宽,又能保持较低的噪声系数. 该设计采用TSMC公司的RF 0.18 μm CMOS工艺,电源电压为1.8 V,功耗为104 mW. 仿真结果表明提出的分布式放大器在2.9~10.6 GHz的频带内S21保持(18.7±0.9)dB的平坦增益,噪声系数最小值NF=1.80 dB.

| Abstract: | This paper proposes a distributed amplifier which can be applied to ultra wide-band (UWB) wireless communication systems. The distributed amplifier can realize the bandwidth extension by using artificial transmission line formed by inductors to absorb parasitic capacitances of the transistors. Benefiting from the wealth of distributed theory, the proposed low noise amplifier (LNA) not only extends its bandwidth but also maintain a low noise figure during operation wideband. This circuit has been designed under TSMC RF 0.18 μm 1P6M process with 1.8 V supply, and the power consumption is 104 mW. Simulation results show that the designed LNA has a flat gain of 18.7 dB from 2.9 GHz to 10.6 GHz with less than 0.9 dB ripple and its minimum noise figure (NF) is only 1.80 dB. |
