摘要：
In this paper, we present a low-power 24 GHz CMOS LNA (Low Noise Amplifier) for automotive collision avoidance radar. The proposed circuit was fabricated using the 65-nm RF CMOS technology and powered by a 1.2 V supply. To decrease the power consumption and increase the voltage gain, a cascode scheme was implemented in this circuit, and it was optimized to decrease the noise figure. Compared to the recently reported LNA, our proposed LNA showed the lowest power consumption and noise figure of 4.59 mW and 2.98 dB, respectively, with a high voltage gain of 24.3 dB. Additionally, it was designed with the smallest chip area of 0.6×0.6 mm2 and a core cell of 0.31×0.35 mm2 without pads. © ICROS 2021.
