A 79GHz 2×2 MIMO PMCW radar SoC in 28nm CMOS

Abstract

This paper describes a 28-nm fully integrated 79 GHz Phase Modulated radar SoC including 2TX, 2RX and the mm-wave frequency generation. A custom digital core generates the pseudo random sequence and performs correlation and accumulation of the digitized received data. With 1 W power consumption, 7.5 cm range resolution is achieved while antennas arrangement allows for 5° resolution over ±60° elevation and azimuth scan in 2×2 code domain MIMO operation.
