Towards passive imaging with CMOS THz cameras

This paper reports on a measurement which shows for the very first time that uncooled non-quasi static detectors with wide bandwidth integrated in a 32 × 32 pixel focal plane array in standard 65 nm bulk CMOS silicon technology are able to detect non-amplified black-body radiation. With its integrated readout electronics, this “THz camera” shows a noise equivalent temperature difference (NETD) of 20.86 K in integration mode.
