Abstract

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.
