This brief gives an overview of recent advancements in CMOS automotive radar sensors, focusing on the most critical circuit design at mm-wave frequencies. Highly scaled CMOS technologies enable very low-power consumption, reduced costs, and higher data processing capacity and integration compared to state-of-the-art SiGe BiCMOS chip-set solutions commonly adopted in commercial products. The very bottleneck is still represented by the radio front-end due to the challenging requirements of long-range radars. Circuit topologies and design tradeoffs are here discussed with reference to critical building blocks of the mm-wave radar front-end, reporting circuit implementations for a 77-GHz long-range radar sensor in a 28-nm fully-depleted silicon-on-insulator CMOS technology.

Abstract

This brief gives an overview of recent advancements in CMOS automotive radar sensors, focusing on the most critical circuit design at mm-wave frequencies. Highly scaled CMOS technologies enable very low-power consumption, reduced costs, and higher data processing capacity and integration compared to state-of-the-art SiGe BiCMOS chip-set solutions commonly adopted in commercial products. The very bottleneck is still represented by the radio front-end due to the challenging requirements of long-range radars. Circuit topologies and design tradeoffs are here discussed with reference to critical building blocks of the mm-wave radar front-end, reporting circuit implementations for a 77-GHz long-range radar sensor in a 28-nm fully-depleted silicon-on-insulator CMOS technology.
