Adifferential D-band (140 GHz) passive imager has been demonstrated in a 65 nm CMOS technology. It achieves a minimum noise equivalent power of 26 fW/√Hz with peak responsivity of 1.2 MV/W. The core circuit consumes chip area of 950 × 240 μm 2 with dc power consumption of 152 mW. This work further pushes imagers in CMOS technology working towards higher millimeter wave/sub millimeter wave frequencies.
