Abstract
A 1 k-pixel camera chip for active terahertz video
recording at room-temperature has been fully integrated in a
65-nm CMOS bulk process technology. The 32x32 pixel array con-
sists of 1024 differential on-chip ring antennas coupled to NMOS
direct detectors operated well-beyond their cutoff frequency based
on the principle of distributed res istive self-mixing. It includes
row and column select and integrate-and-dump circuitry capab le
of capturing terahertz videos up to 500 fps. The camera chip
