Florinel Balteanu (M’98, SM’17) received the M.S. degree in electrical engineering from Polytechnic Institute, Bucharest, Romania, in 1983, and the Ph.D. degree in electrical engineering from Transylvania University, Brasov, Romania, in 1995. From 1983 to 1992, he was with the Institute of Nuclear Research, Pitesti, Romania, working on electronic instrumentation for nuclear power reactors. In 1993, he joined the Department of Electronics, University of Pitesti, Romania, as an Assistant Professor doing research in analog circuits. From 1992 to 1993, he was a Fulbright Visiting Scholar at the Center for Reliable Computing, Stanford University, Stanford, CA. In 1996, he joined Philsar Semiconductor, Ottawa, ON, Canada, as a Senior ASIC Designer, a company later acquired by Conexant Systems, Inc. (now known as Skyworks Solutions, Inc.). His work has been focused on the design of radio circuits for GPS receivers, Bluetooth transceivers and GSM/CDMA cellular transceivers. He is presently a Technical Director with Skyworks Solutions Inc., Irvine, CA and is involved in designing circuits for Envelope Tracking and Front End Modules in CMOS and SOI CMOS. He presented short courses and tutorials as an Invited Speaker at IEEE Microwave Theory and Techniques Society (MTT-S) International Microwave Symposium (IMS) and Asia-Pacific Microwave Conference (APMC). He holds 68 U.S. patents, with several more pending. He is author of the chapter “Envelope Tracking Techniques” in the IET book “Radio Frequency and Microwave Power Amplifiers, Vol. 2: Efficiency and Linearity”.
