Title: This Is Why You Need To Worry About Terminations

Date: August 25, 2021

Time: 10:00am PT / 1:00pm ET

Presented by: Eric Bogatin, Professor, Univ of Colorado, Boulder

Abstract:
The first rule of engineering transmission lines is to build a controlled impedance interconnect. The second rule is to implement a termination strategy for the interconnects based on the routing topology and the drivers and receivers. In our Advanced PCB Design class, we use a simple demonstration test board to illustrate the perils of bad termination and how one small change can dramatically improve signal quality. We also bring the scope measurements into a simulation environment and do a direct measurement-simulation correlation.  I will show examples of measurements from this test board and how we are able to achieve excellent measurement-simulation correlation using extracted driver models.
