摘要

本文设计了一种适用于6.2 ~ 10.6 GHz应用的低功耗CMOS超宽带低噪声放大器。采用同步噪声匹配(SNIM)和自体偏置技术,设计了低电源电压下工作的LNA,以降低功耗。仿真结果表明,在0.62V电源电压下,LNA功耗为3.84mW,最大增益为10 dB,平均噪声系数为4.55 dB。该放大器的最小端口反射参数S11和S22 < -10 dB,而1 dB压缩点为-16.2 dBm。

A fully integrated low power UWB LNA using self-body-bias technique for 6.2–10.6 GHz applications
In this paper, a low power CMOS UWB low noise amplifier (LNA) suitable for 6.2-10.6 GHz application is presented. Using simultaneous noise matching (SNIM) and self-body-bias technique, the proposed LNA is designed to operate with low supply voltage in order to reduce power consumption. The simulated results showed that at 0.62V supply voltage, the LNA consumed 3.84mW with a maximum gain of 10 dB and average noise figure of 4.55 dB over the band of interest. Minimum port reflection parameters, S11 and S22 for the proposed amplifier were found <;-10 dB whereas 1-dB compression point was found at -16.2 dBm.
