- Abstract
- A 77GHz CMOS 4-channels receiver, transmitter with 3-outputs and array antenna architecture is proposed for low cost/small size automotive radar system, and implemented by using 65nm CMOS and LTCC substrate respectively. Measured performance of CMOS transceiver, which included useful functions such as dual operation of long/short range detection, I/Q signal process and gain attenuation when near target detection, shows comparable performances to that of commercial SiGe chips. Especially, the transmitter consumes one third lower power compared to SiGe chips. These results confirm that it may be a promising candidate for low cost and small size car radar system. © 2013 IEEE.
