Bandwidth, Current Load and Power-Rail Measurements

How do you achieve high bandwidth in your measurements while minimizing current load on your DUT? Given that your DUT is a power rail, you really don't want to draw too much current from it., or your measurement system will distort the rail. But these two measurement criteria are at loggerheads with each other. It's a quandary, and it has to do with the fundamental nature of signals on interconnects.

Mitigate RF Pickup In Power Rails

Measuring the noise on a power rail seems to be a straightforward task. However, there are some basic pitfalls that can cause incorrect, or even downright strange, results. Let's look at one of these challenges: RF pickup. We'll demonstrate the effect of RF pickup on a power-rail measurement, and then we'll show you an effective means of mitigating that effect.

Validating IBIS Models with Measurements

At the University of Colorado, Eric Bogatin and students Thomas Rutkowski and Huy Nguyen look for a way to validate IBIS models, bringing measured data from a scope into a simulation environment. This article includes an explanation of how the team compared predicted results of the IBIS model supplied by the vendor, the results from a generic model, and measured results from a randomly selected part.

A Design Rule Check List

No matter how well you understand the design principles, and no matter how much experience you have in designing boards, it’s easy for some problems to slip through the cracks because you just forgot to check that feature, or your design is just too big to manually check. This is where a design rule checker comes in.

First ever IEEE P370 Plug Fest Draws a Crowd

The IEEE P370 standards group was formed over four years ago to draft a standard for the Electrical Characterization of PCB interconnects up to 50 GHz. On Monday, Jan 30, 2018, more than 30 engineers attended the organization’s first “plug fest” at the Santa Clara Convention Center to exercise some of the features of the proposed standard.

Two New Open Source Tools for De-embedding

At DesignCon 2018, the IEEE P370 standards group announced the release of two important tools to assist all engineers for de-embedding. In the presentation by Jason Ellison and Heidi Barnes, “A NIST Traceable PCB Kit for Evaluating the Accuracy of De-Embedding Algorithms and Corresponding Metrics”, the two new tools were announced, a board kit and a de-embedding software tool.
