Abstract

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.
