Low-EVM High-Bandwidth Efficient CMOS RF-Transmitters Video
In order to support the increasing demand for data-rich wireless streaming over the airwaves, complex modulation schemes with high peak-to-average ratio and wide channel bandwidth are often used. Such schemes have casted its shadow on the complexity of RF radios, particularly transmitters, in their ability handle such complex modulations while maintaining the required high signal integrity (in the form of stringent EVM and emission mask requirements) and still be power efficient. This talk walks the audience through the various challenges facing today’s modern RF transmitters to deliver such stringent requirements. Several digital and analog CMOS RF transmitter schemes with Digital Pre-Distortion (DPD) are discussed for their potential to address the challenge that lies ahead.
Osama Shanaa: (IEEE S’94, M’01, SM’03) has been with Mediatek as a Senior RFIC Design Director since 2008, where he is responsible for various CMOS RF SoC developments for both cellular and connectivity. He received his BSc. degree in electrical engineering with high honor from University of Jordan in 1992, the M.S.EE degree from Portland State University in 1996 and the Ph.D. degree in electrical engineering from Stanford University in 2001. Between 1995-2008 he held various IC design positions at Radio Comm. Corp., National Semiconductor, and Maxim Integrated Products, where he lead many successful RF wireless designs for PCS, CDMA, WCDMA, WLAN and WiMax. In 2005 he was a visiting professor at the University of California Berkeley where he taught an advanced circuit design class for wireless communications. Dr. Shanaa is a Fulbright scholar, a member of the Etta Kappa Nu honor society and is a senior IEEE member. He currently serves on the Technical Program Committee and the Steering Committee of the IEEE RFIC Symposium. Dr. Shanaa is a former Associate Editor for the IEEE Transactions on Microwave Theory and Techniques and a Distinguished Lecturer for the IEEE Solid-State Circuits Society.
