“…SRR은 24 GHz 대역과 79 GHz 대역의 UWB 방식을 사용하였고, LRR은 77 GHz 대역의 FMCW 방식을 사용해 왔으나, 향후 SRR과 LRR을 통합한 하나의 레이더 시스템으로 구 현되어 널리 사용될 전망이다 [2] . 특히, 77 [5] . 하지만 최근 CMOS 공정 기 술의 발전으로 밀리미터파 분야에서도 CMOS 공정 을 이용한 차량용 레이더 송수신기의 개발이 활발히 진행되고 있다 [6] .…”

This work presents a 77 GHz low noise amplifier(LNA) for automotive radar systems using 65 nm RF CMOS process. The LNA is composed of three stage common source amplifiers and includes transmission line matching networks. To reduce the time for three dimensional EM simulation, we optimize the transmission line impedance matching network using a pre-built EM library. The proposed compact simulation technique is confirmed by measurement results.The peak gain of the LNA is 10 dB at 77 GHz and input/output return losses are below -10 dB around the design frequency.Key words : 77 GHz, Low Noise Amplifier, EM Simulation, Automotive Radar .
