This is part of a planned expansion of the department in the area of CAD for VLSI. Ottawa-Carleton Centre for Communications Research The newly formed Ottawa-Carleton Centre for Communications Research (OCCCR) is a multidisciplinary interdepartmental research group comprising faculty members, full-time research staff, postdoctoral fellows, visiting researchers, graduate students, and support staff from both Carleton University and the University of Ottawa. It is part of the Centre of Excellence "TRIO" (Telecommunications Research Institute of Ontario). Current research areas of the centre with major participation from the department are: integrated services digital networks, mobile and portable wireless networks, and VLSI in communications. Micronet The department is a member, along with seven other Canadian universities and several major industrial organizations, of Micronet, the federally-sponsored network on Microelectronic Devices, Circuits and Systems for ULSI (ultra-large scale integration). Within the department Micronet supports research on: device structures, modeling and fabrication processes for submicron CMOS and BiCMOS IC's; high-speed filters, phase detectors, A-to-D converters, frequency synthesizers and other circuit elements for silicon IC's operating at radio frequencies; analysis and optimization of interconnects for high-speed IC's; and automated generation of custom cells for VLSI design. The structure of the courses offered allows a well-integrated master's or Ph.D. program of study to be chosen appropriately related to the field of thesis research. Device- and integrated-circuit-oriented courses cover: fabrication, semiconductor device theory, semiconductor device design, integrated circuit design and integrated circuit reliability. Circuit-oriented courses include: signal-processing electronics, micro-processor electronics, computer-aided circuit design, phase-locked circuits, filter circuits, RF and microwave circuits, antenna and array design.
