Continued integration of various devices on to a single semiconductor substrate as well as the scaling of those devices to ever smaller feature sizes have opened up a new design space for system level innovations that are no longer constrained by many of the restrictions of discreet system design. This talk will present design methodologies for integrated power generation and radiation at mm-wave frequencies that are enabled by this continued integration of various electronic and electromagnetic (EM) structures onto the same substrate. One benefit of this integration available to mm-wave designers is the vast computational power available on chip. A fully integrated self-healing power amplifier at 28 GHz in 45nm SOI CMOS takes advantage of this processing power to heal the PA against process variation, mismatch, environmental variation and transistor failure. Continuing with the observation that transistors and their connections to EM radiating structures on an integrated substrate are essentially free, the concept of multi-port driven (MPD) radiators is introduced, and proof of concept mm-wave radiators using 130nm SiGe BiCMOS and silicon photonics are demonstrated. Steven M. Bowers received his B.S. in Electrical Engineering from the University of California, San Diego and his M.S. and Ph.D. in mm-wave circuits and systems from the California Institute of Technology, where he is currently working as a postdoctoral fellow.
