ECE M.S. student Outmane Lemtiri Chlieh has received a 2012 IEEE Microwave Theory and Techniques Society BS/MS Scholarship.
A master's degree student in John Papapolymerou's research group, Mr. Chlieh works with CMOS Ultra-Wide-Band Active Baluns, an RF device that can convert a differential signal at the input to a single ended signal at the output. The advantage of active baluns compared to passive ones is that they provide some positive gain in order to compensate for any eventual loss, and CMOS offers the possibility of shrinking the size of a chip so that it can be used in a variety of applications. Some of these applications are connecting balanced devices such as television receivers, dipole antennas,or parallel wire transmission lines to unbalanced devices such as coaxial cables, coaxial transmission lines, or coaxial antenna systems.
