摘要

采用45 nm SOI CMOS技术制备的18mw有源毫米波反射器在77 GHz时的峰值增益为20 dB，在75.5 ~ 80.5 GHz范围内的5 GHz带宽为3 dB，在同一频段内的噪声系数为50-Ω，为7.5 ~ 8.5 dB。它由一个LNA，一个BPSK调制器和两个可变增益输出级组成，每个输出级驱动一个单独的发射天线。该芯片占地570µm×880µm，倒装在一个7mm×7mm柔性中间体上，具有两个发射天线和一个接收天线。

A 77-GHz active millimeter-wave reflector for FMCW radar

An 18-mW active millimeter-wave reflector fabricated in 45-nm SOI CMOS technology exhibits a peak gain of 20 dB at 77 GHz, a 3-dB bandwidth of 5 GHz from 75.5 to 80.5 GHz, and a 50-Ω noise figure of 7.5–8.5 dB over the same frequency band. It consists of an LNA, a BPSK modulator and two variable gain output stages each driving a separate transmit antenna. The chip occupies 570µm×880µm and is flip-chip mounted on a 7mm×7mm flexible interposer with two transmit and one receive antenna.
