This paper describes general considerations for the design of highly efficient and distributed room-temperature Terahertz detectors and transmitters in (Bi)CMOS technologies. It discusses the design of industrial-grade scalable terahertz imaging systems. This necessitates a deep understanding of the process technologies front-end and the back-end, as well employing innovative architectures of terahertz...
Future imaging applications in the submillimeter-Wave range (300GHz to 3THz) require RF systems that can achieve high sensitivity and portability at low power consumption levels. In particular, CMOS process technologies are attractive due to their low price tag for industrial, surveillance, scientific, and medical applications. Recently, CMOS-based detectors have shown good sensitivity up to 1THz...
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 consists of 1024 differential on-chip ring antennas coupled to NMOS direct detectors operated well-beyond their cutoff frequency based on the principle of distributed resistive self-mixing. It includes row and column select and integrate-and-dump...
