IEEE Ottawa Section: MTT-S / AP-S Chapter presents:
Title: Characterization and Modeling of GaN HEMT Trapping Effects for Microwave Circuit Design
Date: September 2nd, 2020
Time: 11 AM (ET)

This talk will review some recent advancements achieved on the characterization and modelling of the trapping effects felt in GaN HEMT transistors, and their impact on microwave circuit design. Because of their nowadays importance, a particular attention will be payed to applications on high power amplifiers for mobile wireless infrastructure and pulsed radar applications.
For that, the talk will start by recollecting the most common model formulations adopted for the various levels of RF engineering, from the device level (physics) to the transistor (circuit) and amplifier (system) level. Starting by the Shockley-Read-Hall capture and emission processes we will be able to understand one of the fundamental signatures of trapping effects, the significantly different charge and discharging time constants, and its impact on power amplifier nonlinear distortion behavior. Then, some widely adopted approaches of the channel current transients’ characterization are addressed and the talk concludes by presenting some illustrative cases of application to RF high power amplifiers.

Topic: Technology-Enabled Indigenous and Remote Communities
Registration:Â https://events.vtools.ieee.org/m/238665Â
Summary:
As the COVID-19 Pandemic demonstrated, almost all Indigenous and remote communities suffered from serious infrastructure deficits. With limited or unreliable Internet, poor quality electricity, and weak health care services, these communities were uniquely vulnerable to the disease and the economic and social challenges that accompanied the pandemic. But Canadians already knew that Indigenous and remote communities are poorly served and largely lift out of the so-called “innovation economy.” It is time to develop a strategy for bringing technology-enabled opportunities to Indigenous and remote communities. This webinar presents a model for digitally-enabled Indigenous and remote communities, explores the barriers to implementing this “inversion” of Canadian innovation and that contemplates strategies for addressing quality of life issues in collaboration with residents and local governments.
Biography:
Ken Coates is Canada Research Chair in Regional Innovation at the Johnson-Shoyama Graduate School of Public Policy, University of Saskatchewan. His work focuses on the development of strategies to promote 21st century well-being in small town, rural, Indigenous and remote Canada. Ken’s major project examines the potential contributions — and negative impacts — of emerging technologies on rural and remote communities.
