Future big-data oriented commuting requires energy efficient big-data communication. This talk will address this challenge by exploring electrical communication solution at millimeter-wave and sub-Terahertz (~100GHz) with source, transmission and detector all realized in CMOS. We will show that with the use of meta-device (CRLH tline, split-ring, spoof surface plasmon), one can effectively manipulate the EM-field phase such that phase-controlled devices (CRLH tline, split-ring) can be utilized to combine output power (3-5dBm) of coupled oscillator sources as well as in detection (-78 dbm). And surface-plasmonic device can be utilized for low-crosstalk (-21dB) and high data-rate (25Gbps) on-chip transmission. Demonstrated chips will be presented with measurements at 140GHz and 280GHz by standard 65nm CMOS process. What is more, the application in 140GHz wireless links using phase-arrayed beamforming will also be reported.
