There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Abstract:
The objective of the proposed research is to apply theoretical analysis and Machine Learning techniques to develop a class of solutions we call the BCOD for a variety of mm-wave design tasks, including Impedance Transforming Baluns, Power Combiners, Out-phasing circuits, and Doherty networks. The BCOD structure is an extension of a Marchand balun with a shorter electrical length and lumped capacitors. In this thesis, we analyze the network requirements of the mm-Wave tasks, apply mathematical constraints, solve for theoretical solutions on the BCOD structure, and calculate optimum electrical parameters to resolve the mm-Wave design tasks. To implement theoretical microwave structures in physical realizations, researchers often employ time-consuming techniques based on trial-and-error to tune EM parameters. We attempt to break this prolonged process by learning from data and employing Machine Learning techniques. We propose to develop a database of transmission-line and coupled-line implementations, build Machine Learning models that learn Electronic-EM relationships, and utilize optimizers to directly transform from electrical parameters to optimum physical dimensions with lowest loss. The goal is to fully automate a design flow that instantaneously generates a full EM design when given a specification of relevant mm-Wave tasks.
