RF/Microwave Training Webinar Series

Title: Spur-Free Switching Power Converters for Analog and RF Loads

Date: September 18, 2012

Time: 8am PT/ 11am ET/ 3pm UTC

Presented by: Besser Associates

Sponsored by: AWR Corp.

Description:
A critical aspect of lowering the power consumption in communication and navigation devices is the process of converting power from the battery to the various loads in the system. However, the noise-sensitive RF circuitry in these devices is limiting the use of efficient energy conversion schemes, such as switching power converters, due to the significant switching noise associated with them. This webinar will discuss various power conversion techniques used for powering of noise-sensitive analog/RF loads and the most recent advancement in the design of RF-friendly spur-free switching power converters that enable powering RF PAs directly from buck converters without compromising mixing or interference specifications.

Outline:
- Definitions & Tasks
- Power Regulation Circuits – Linear and Switching Regulators
- The spurious noise problem
- Spurious noise mitigation techniques for powering RF circuits
- Recent Advancements - Spur-free switching power converters

Presenter: Dr. Ayman Fayed
Ayman Fayed received his B.Sc. in Electrical Engineering from Cairo University, Egypt in 1998, and the M.Sc. and Ph.D. degrees in Electrical & Computer Engineering from The Ohio State University, Columbus, Ohio in 2000 and 2004 respectively. Since 2009, he has been an assistant professor at the Dept. of Electrical & Computer Engineering, Iowa State University, Ames, Iowa. His research interests include power management/conversion solutions for RF mixed-signal SoCs and multi-core processors, and energy harvesting for power-restricted and remotely-deployed devices. From 2000 to 2009, Prof. Fayed held several technical positions at Texas Instruments Inc., where he was a key contributor to many product lines in nanometer CMOS technologies for both wire-line and wireless applications. Most recently, he was a member of the technical staff with the wireless analog technology center at TI, where he led several key projects in 65nm and 45nm CMOS technologies including fully integrated power management system and circuit solutions for mixed-signal SoCs with mutli-RF cores. Dr. Fayed has many publications and patents in the field and has authored a book in the area of adaptive systems titled “Adaptive Techniques for Mixed Signal System On Chip” (Springer 2006). He is a senior member of IEEE, and serves as a reviewer for many IEEE journals and international conferences in the area of power management and analog circuit design. Ayman Fayed is presenting the following public course for Besser Associates: Power Conversion & Regulation Circuits for VLSI Systems : February 25-28, 2013 in San Diego, CA.
