The Communications Circuits Laboratory conducts coordinated teaching and research in analog/RF design. Through a sequence of lab-oriented courses, students design, build, and test complete radios at VHF through microwave frequencies each semester. This gives our graduates the practical, hands-on experience necessary for this field of engineering. Our research efforts have been primarily focused on design of transceivers in integrated circuit form, with special emphasis on the modeling and application of high-Q spiral inductors. Students and faculty have experience with standard bulk-CMOS, newer Silicon-on-Insulator (SOI) and Silicon-on-Sapphire (SOS), and GaAs processes. Designs are created with tools from both Agilent and Cadence and tested at the board and chip levels with industry-calibre measurement equipment and probing stations.
