A 77 GHz 90 nm CMOS Transceiver for FMCW Radar Applications

 

Abstract

The first 77 GHz frequency modulated continuous wave (FMCW) radar transceiver IC with an accurate FMCW signal generator using a 90 nm CMOS process is presented. To realize accurate FMCW radar system in CMOS, a PLL synthesizer that is able to output linear FMCW frequency sweep with digitaloriented frequency reference is applied. Measured radar performances, output spectrum and distance of a target, show the transceiver achieves a fundamental function for radar applications.
