Welcome to the DesignCon 2020 agenda and presentation download site. Here you can view and download conference and/or Chiphead Theater presentations before, during, and after the event. If you’re looking for a presentation from a specific session that you’re unable to find here, it is likely because the presenter has not provided permission for external use or has not yet shared their presentation with us. Please check back after the event for a more complete catalogue of available presentations.
Everyone has used a TDR. The results are simple to analyze when it's a simple transmission line built with an adjacent return plane. But what if the return plane is not adjacent?
The test structure we will explore is a simple 4-layer board with a micro strip on top and three planes underneath. What happens to the TDR response, and the impedance we measure for the signal line when the signal is launched between the signal line and the top plane, or the signal line and the middle or bottom plane? Is the plane just a reference? Does it matter between which planes the TDR is connected?
If you want to test your understanding, come to this speed training event and see this live demo and test yourself against the real world. All will be made clear in this performance.
