Mentor White Paper: Characteristic vs. Instantaneous Impedance


Reading time ( words)

Successful signal integrity analysis depends on a fundamental concept: impedance. Without a thorough understanding of the impedance values that a signal encounters along the way, designers cannot maintain good signal quality from source to receiver. 

This paper defines the difference between characteristic and instantaneous impedance and explores the essential principles of impedance and design-controlled impedance.

Advanced Stackup Planning with Impedance, Delay and Loss Validation

08/02/2018 | Yuriy Shlepnev, Simberian
A typical PCB design usually starts with the material selection and stackup definition—the stackup planning or design exploration stage. How reliable are the data provided by the material vendors and PCB manufacturers? Can we use these data to predict trace width and spacing for the target trace impedance or to calculate delays or evaluate the loss budget?

Software Bytes: Having Fun With Impedance

08/03/2016 | Abby Monaco, Intercept Technology
About a year ago, I was assigned a new project: become an expert in impedance, more or less. I had no idea how much this research would bring out the nerd in me. Even if you don’t typically design controlled-impedance circuit boards, you probably will eventually. Read on!
