CMOS Platform for Terahertz

The Complementary Metal Oxide Semiconductor (CMOS) integrated circuits technology has emerged as a means for realization of capable and affordable systems that operate at 300 GHz and higher. This is bridging the Terahertz Gap and enabling everyday life applications utilizing this portion of the spectrum. Signal generation up to 1.3 THz, coherent detection up to 1.2 THz, and incoherent detection up to ~10 THz have been demonstrated using CMOS. Furthermore, a highly integrated rotational spectroscopy transceiver for electronic smelling operating up to near 300 GHz, a 30-Gbps 300-GHz QPSK transmitter for data communication with an output power of −6 dBm and an imaging array operating at 820 GHz have been demonstrated in CMOS. These along with the data in the literature suggest that the necessary terahertz electronics for everyday life applications can be affordably manufactured.
