摘要

本文讨论了一种用于唤醒接收机的超宽带低噪声放大器的设计。LNA电路采用RF-TSMC CMOS 0.18µm，适用于3 - 9ghz频率范围。为了降低噪声系数，增加了衬底电阻。改进后的LNA实现了1.66 dB的低噪声系数，比原电路提高了47%，在工作频率范围内的最大功率增益为21.02 dB。设计的LNA在1V时功耗为12.3mW。

An Ultra-Wideband noise-reduction LNA With Variable Gain for Wireless Wake-up Receivers

The design of an ultra-wideband low-noise amplifier for wake-up receiver applications is discussed in this article. The LNA circuit is developed for the 3–9 GHz frequency ranges using RF-TSMC CMOS 0.18µm. To lower the noise figure, substrate resistance is added. The improved LNA achieves a low noise figure of 1.66 dB, which is 47% better than the original circuit, and a maximum power gain of 21.02 dB over the operating frequency range. The designed LNA dissipates 12.3mW at 1V.
