Integrated Sys Seminar-Traveling Wave Si ICs for High-Speed Comm. (Prof. Jim Buckwalter, UCSD)

Speaker - Prof. James Buckwalter (UCSD)Abstract:Traveling wave structures are appealing for high-speed (>40Gbs) and high-frequency (>60GHz) communication circuits implemented with highly-scaled CMOS/BiCMOS processes because of the reduced passive area required for broadband matching. Broadband millimeter traveling wave approaches are discussed in this talk and novel schemes for improving the performance of traveling wave structures are presented. First, trade-offs between traveling wave and lumped circuits are described and loss-compensation for equalized frequency response is presented. Second, a 30dB, W-Band cascaded constructive wave amplifier is discussed that sets new records for the achievable gain in a silicon technology. Finally, a 10dB, 102GHz amplifier is presented for broadband circuit applications.
