GTL 122a, b - Fundamental Principles of Signal Integrity
  GTL 122a: Fundamental Principles of Signal Integrity
GTL 122b: Fundamental Principles of Transmission Lines
 

This two day, lecture/demo course, is a practical introduction to the general principles used over and over in all aspects of signal integrity. Most of the problems associated with how high speed signals are distorted by the physical interconnects can be analyzed and solved based on six basic principles: bandwidth and rise time, impedance, inductance, characteristic impedance, cross talk and differential impedance. If you have ever been confused about what these topics really mean, and you want to have an intuitive understanding, this course is for you.

These basic concepts, at the foundation of signal integrity, are presented in a clear, simple, yet precise, engineering format. The mathematics is stripped away to reveal the underlying mechanism of how the physical design and materials' properties affect signal integrity. Each of these principles is illustrated by demonstrations of measurements or simulations using examples such as IC packages, connectors, printed circuit boards and cables.

This foundation building course should be the starting place for anyone who wishes to have an intuitive understanding of how interconnect design will affect signal integrity.

Why this class is important for you: The electrical performance of interconnects dramatically affects signal integrity in all high-speed digital, rf and telecomm applications today. The design process is an intuitive and creative process. While it is critically important to have the skills to be able to use numerical simulation tools for accurate predictions of how the interconnect design will affect signal integrity, it is also important to have an intuitive understanding so that you can unlock your creativity to find solutions to meet higher speed applications with shorter product design windows.

If you are a signal integrity engineer, this course will help you be more creative. If you are a non-electrical engineer, this course will provide a solid foundation so you will understand the important issues and how physical design influences signal integrity.

This class is taught by Dr. Eric Bogatin.
