Abstract

A fully-integrated low-power and compact FMCW transmitter for automotive radar is presented. It consists of a passive mixer-based frequency multiplier, a push-push frequency doubler, an injection-locked power amplifier and a power amplifier. The input frequency (19-20.25GHz) of the transmitter is multiplied by 4 to produce an output frequency ranging from 76-81GHz. The design has been fabricated using 22nm FDSOI process. The minimum measured output power from 76-81GHz is 10.5dBm to 8dBm. The measured 1MHz offset phase noise is −109dBc/Hz. The total power consumption is 88.5mW and the chip occupied an area of merely 430µm×150µm.

用于22nm FDSOI汽车雷达的低功耗、紧凑型76-81GHz FMCW发射机

介绍了一种用于汽车雷达的全集成、低功耗、紧凑型FMCW发射机。它由基于无源混频器的倍频器、推推倍频器、注入锁定功率放大器和功率放大器组成。将发射机的输入频率(19-20.25GHz)乘以4，得到76-81GHz的输出频率。该设计采用22nm FDSOI工艺制作。在76-81GHz范围内，最小测量输出功率为10.5dBm ~ 8dBm。测量到的1MHz偏置相位噪声为−109dBc/Hz。总功耗为88.5mW，芯片占地面积仅为430µm×150µm。
