A Fully Integrated 78 GHz Automotive Radar System-an-Chip in 22nm FD-SOI CMOS

Next generation automotive radar sensors are increasingly becoming sensitive to cost and size, which will leverage monolithically integrated Radar System-on-Chips (RadarSoC). This paper presents a 76–81 GHz RadarSoC as an evaluation vehicle for an automotive 22nm fully-depleted silicon-over-insulator (FD-SOI) CMOS technology. It features a digitally controlled oscillator, two millimeter wave transmit channels and receive channels, an analog base-band with analog-to-digital conversion as well as a digital signal processing unit with on-chip memory.
