Ultrahigh-Speed Terahertz Transceiver with CMOS Technology

Ultrahigh-speed wireless communication of 100 Gb/s class can be realized with the 300-GHz band which is a part of terahertz since a wide frequency band can be used. We have realized a one-chip CMOS transceiver using this 300-GHz band. The high frequency performance of the transistors in the CMOS integrated circuits is inferior to that of the compound integrated circuits. To overcome it, we have developed a circuit to operate the transceiver beyond the maximum operating frequency of the transistor. We have also developed a module for connecting an integrated circuit to an external horn antenna. In this paper, we will also discuss the future application of terahertz communication compared with conventional wireless communication.
