Fields-CQAM Public Lectures: What is missing from common practice in machine learning? @ Carleton University
Jun 20 @ 19:00 – 20:00

Fields-CQAM Public Lectures: Ali Ghodsi, University of Waterloo

 

What is missing from common practice in machine learning?

AI, and machine learning in particular, is enjoying its golden age. Machine learning has changed the face of the world over the past two decades but we are still a long way from achieving a general artificial intelligence. In this talk, I will discuss a couple of elements that I believe are missing from common practice in machine learning, including incorporating causality and creating a new framework for unsupervised learning.

Transceiver Architectures for Beyond-5G: Challenges and R&D Opportunities, co-organized with SSC-S
May 14 @ 12:00 – 13:00

Presented by IEEE MTT-S Distinguished Microwave Lecturer (DML) Talks:

Transceiver Architectures for Beyond-5G: Challenges and R&D Opportunities, co-organized with SSC-S

By
Dr. Payam Heydari
University of California, Irvine

Date: Thursday, May 14 , 2020

Time: 12:00 PM – 1 PM

Abstract:

The ongoing super-linear growth of world’s population coupled with the worldwide access to internet and the general public’s tendency to use more bandwidth-intensive applications fuel the urgency to enhance wireless infrastructures so as to meet these demands. Consequently, the wireless R&D is headed towards the inception of “Beyond-5G” (e.g., 6G) technology.  This webinar provides a comprehensive overview of challenges and opportunities in designing beyond-5G transceiver architectures capable of achieving high data rates above and beyond 20 Gbps.

Abstract

5G connectivity is the next technological revolution. This pervasive, ultrafast compute network will connect billions of devices with data on-demand. It will drive economic expansion in many sectors, spawn new products and services, and transform our lives as we know it. Yet, before 5G can deliver on its promises and quality of service (QoS) metrics, wireless systems designers and engineers must overcome sizable challenges.  

Ansys 5G simulation solutions empower these individuals to solve the complexities impeding device, network and data center design. Ansys 5G simulation solutions provide electromagnetics, semiconductor, electronics cooling and mechanical analysis tools to accurately simulate 5G radio and related technologies. The multi-solution platform leverages high-performance computing that can be deployed across the enterprise, allowing designers and engineering experts to collaborate more effectively. 

This seminar will highlight the following 5G engineering challenges: 

·  End User Equipment  

    o   multi-frequency band antenna integration 

    o   modeling of mm-wave array antennas  

    o   RFI, EMI & Desense Mitigation 

·  Base-Station Antenna Modeling 

    o  Full Communication Analysis in Electrically Large & Complex Environment 

    o  RFI, Data Coverage & ElectroThermal Reliability

Characterization and Modeling of GaN HEMT Trapping Effects for Microwave Circuit Design
Sep 2 @ 11:00 – 12:00

 

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)

Register at: https://events.vtools.ieee.org/m/238482

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.
