在这项工作中，300-GHz的7×7成像探测器阵列已开发与65-nm CMOS工艺。每个像素是由一个相同的300 GHz的共栅差分直接检测器与贴片天线集成。模拟结果表明，该探测器的响应度为1,200 V/W，NEP为20 pW/Hz 05。芯片面积为4×4 mm 2，包括焊盘。利用所制备的7×7探测器阵列作为探测器，成功实现了300 GHz的实时反射成像。
In this work, a 300-GHz 7×7 imaging detector array has been developed with a 65-nm CMOS technology. Each pixel is made of an identical 300-GHz common-gate differential direct detector integrated with a patch antenna. The detector exhibits a 1,200 V/W responsivity and a 20 pW/Hz05 NEP by simulation. The fabricated chip area is 4×4 mm2 including wire-bonding pads. Employing the fabricated 7×7 detector array as a detector, real-time reflection imaging at 300 GHz was successfully carried out.
