Designing for Stability in High Frequency Circuits

High-frequency circuit designers often struggle with stability. Learn techniques to identify and solve stability problems in the design phase before they become headaches in the lab. Classical methodologies will be discussed, and a unique approach will be introduced using a bidirectional impedance probe in PathWave Advanced Design System (ADS) called the “Winslow Probe”. 

Learnings: 

• Review of basic theory and classical techniques for circuit-level stability analysis
• Using a bidirectional impedance probe to understand and solve stability problems in your design 
• Circuit examples illustrating the use of the Winslow Probe to tackle stability problems

Matt Ozalas
RF Power Amplifier & Module Design Expert
Keysight Technologies

Matt received his BSEE from Penn State University in 2001 and his MSEE and MBA from Arizona State University in 2010. From 2001 to 2005, he worked at the Mitre Corporation where he did RFIC and Power Amplifier Design for a variety of high frequency applications. From 2005-2013, he worked at Skyworks Solutions in the Santa Rosa Design Center, designing and developing high volume multiband power amplifier and front end modules for wireless handsets. He joined Keysight EEsof EDA in 2013, where he is currently working as an Application Developer and Product Owner for ADS.?

Thomas A. Winslow
Distinguished Fellow of Technology
MACOM

Thomas Winslow completed his PhD in Electrical Engineering at North Carolina State University in 1993. After graduation, he joined the ITT-Gallium Arsenide Technology Center in Roanoke, Virginia designing complex Transmit/Receive chips, LNAs, and handset power amplifiers until MACOM acquired the ITT-GTC design center. After joining MACOM, he specialized in high voltage Gallium Arsenide power amplifiers for RADAR applications. After a period of time with Nitronex and Hittite developing broadband GaN power amplifier MMICs, he returned to MACOM, and is currently a Distinguished Fellow of Technology, developing a variety of amplifier products in GaAs and GaN technologies.

He has published 29 papers, holds 13 patents, is a Senior Member of the IEEE, and is on the editorial board of the Journal of RF and Microwave Computer-Aided-Engineering.
