Short-Millimeter-Wave CMOS Design for Ultrahigh-Speed Wireless Communication

Abstract

Recently, short-distance high-speed wireless communication using a 60 GHz band has been studied for mobile application. To realize higher-speed wireless communication while maintaining low power consumption for mobile application, however, a short-millimeter-wave band (more than 100 GHz) is used since it can potentially provide a wider frequency band. Thus, we have studied D-band (110 - 170 GHz) CMOS circuits to realize low-power ultrahigh-speed wireless communication. In the short-millimeter-wave band, since only an insufficient device model is provided, research has to start from device modeling. In this paper, our studies of modeling and design for D-band CMOS circuits are described. Finally, a 10 Gbps, 135 GHz wireless transceiver with a power consumption of 98 mW is demonstrated.
