Presented by: Eric Bogatin, Professor, Univ of Colorado, Boulder
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.
Eric Bogatin received his BS in physics from MIT and MS and PhD in physics from the University of Arizona in Tucson. He has held senior engineering and management positions at Bell Labs, Raychem, Sun Microsystems, Ansoft and Teledyne LeCroy. He has written seven technical books in the field and presented classes and lectures on signal integrity worldwide.
He is currently a professor in the ECEE dept at the University of Colorado, Boulder, the technical editor of the SI Journal and a Fellow at Teledyne LeCroy.
