Prior to 1982, he worked for a number of companies including nearly four years with Atomic Energy of Canada, and shorter periods with Xerox, Valcom, Central Dynamics and Philips. From 1982 to 1984 he worked with Bell-Northern Research doing analog circuit design. In 1989 he joined the Department of Electronics, Carleton University, Ottawa, Canada, where he is now a Professor. For some years, he did consulting work for Nortel Networks in RFIC design. For the last number of years, he has been involved in collaborative research which involved numerous graduate and undergraduate students and various companies including Nortel Networks, Sige Semiconductor, Philsar, Conexant, Skyworks, IBM and Gennum. He has authored or co-authored about 105 technical papers which have appeared in international journals and conferences. He is a co-author of the books Radio Frequency Integrated Circuit Design (Artech House 2003) Radio Frequency Integrated Circuit Design 2nd Ed. (Artech House 2010) and Integrated Circuit Design for High-Speed Frequency Synthesis (Artech House 2006). His research interests include the design of analog and radio-frequency integrated circuits, including filter design, and communications applications.
Dr. Plett is a member of AES and PEO and has been the faculty advisor to the student branch of the IEEE at Carleton University for about 20 years. He was the co-author of papers that won the best student paper awards at BCTM 1999 and at RFIC 2002.
