Event Description

Signal Integrity Webinar Series

Title: Signal Integrity and Electromagnetic Interference Modeling of a Smartwatch

Date: July 18, 2017

Time: 8am PT / 11am ET

Sponsored by: CST - Computer Simulation Technology

Presented by: Patrick DeRoy, CST of America LLC


In this webinar, we will demonstrate how structural and electromagnetic simulation tools can be used to co-design many functional aspects of a smartwatch. We will look into the various design aspects that require close collaboration between electromagnetic and structural design teams as well as those design aspects that can be carried out independently. In particular, we will discuss the design of a LVDS connector interface and an integrated GSM antenna to meet signal integrity and RF performance specifications respectively and the use of EMI mitigation techniques to meet compliance requirements.

Presenter Bio:

Patrick DeRoy completed his B.S. and M.S. degrees in Electrical and Computer Engineering from UMASS Amherst in 2012. His coursework focused primarily on microwave engineering, but he now focuses on the field of Electromagnetic Compatibility. He completed his Master’s with CST, investigating cable shielding and transfer impedance modeling, correlating simulation and measurement results. He is an Application Engineer, primarily supporting customers modeling EMC problems ranging from emissions on power electronics PCBs, to larger scale problems such as lightning strike. A growing area of interest and increasing focus is simulation of Signal and Power Integrity at the IC package and PCB level, as well as interference between RF and high speed digital systems.
