Abstract
This paper proposes a low-power 24-GHz CMOS down-conversion mixer for the automotive radar. This circuit operates at the operation frequency of 24 GHz, and it contains low-power circuit technique. The proposed circuit is also fabricated using 65-nm RF CMOS(radio frequeny complementary metal-oxide-semiconductor) process. The circuit is powered using a 1.2-V supply with the bias voltage of 0.8 V for the low-power technique. This circuit also has fully-differential scheme to reduce RF noise, and harmonic distortions. The proposed mixer showed lower power dissipation of 6.5 mW with a high conversion gain and very small chip area of 0.01 mm2 as compared to conventional research results.
