A High Performance Low Cost CMOS Radar for Advanced Driving Assistance Applications

Abstract

We present a low cost, flexible digital radar operating at 76 GHz-77 GHz frequency band (global harmonized), supporting both short range and long range automotive radar applications, such as adaptive cruise control, blind spot detection, collision warning and mitigation, etc.. The highly integrated millimeter wave transceiver is built on 65 nm CMOS process containing multiple transmit and receive chains operating in an array processing mode and supporting fully digital waveform generation and receive signal processing. While based on a standard low cost, low power CMOS process, the system also introduces an innovative packaging solution and novel antenna design that allow a viable, cost effective solution for mass vehicle market.
