Paper Abstract

We report on active imaging with CMOS transistors at 300 GHz and 1.05 THz. Two basic focal plane arrays consisting of nMOS transistors and wide-band bow-tie antennas have been implemented in a low-cost 130 nm CMOS technology. Raster scan imaging of objects concealed in a paper envelope has been achieved at 300 GHz with a commercial radiation source. The images clearly reveal the concealed objects with a dynamic range of 35 dB and a resolution of 3 mm. At 1.05 THz, the pixels achieve a responsivity of 50 V/W and a noise equivalent power of 900 pW/Hz0.5.
