My aging vibration system started faulting. Shaking for 30 years takes a toll on a thing, after all. The system is pretty straightforward, just a big stack of audio amps and a controller. Much to my lab manager’s chagrin, I had been intentionally ignoring the warning signs.

The power electronics engineer and the power integrity engineer share a common goal: provide the system with the correct voltages, currents, and noise characteristics to achieve the desired performance. Unfortunately, they do not share much else. They generally use different tools, vocabulary, and figures of merit. As a result, both sides lose.

Target impedance has become a standard tool when designing a power distribution network (PDN). It establishes a limit to the highest impedance the power rail on the die should see looking into the PDN. If the PDN impedance stays below this limit, even the worst-case transient current from the die will generate an acceptably low rail voltage noise.

When measuring low impedance with the two-port shunt-through configuration, we potentially create an error due to the resistance of cable braids.  This error can be reduced or eliminated by using appropriate preamplifiers. There are professional preamplifiers on the market that do a great job reducing the cable braid error.  If you want to experiment with your own circuit, this article will help you

The paper discusses the development of GDDR6 as a lower-risk and more cost-effective solution as compared to other high-bandwidth memory solutions.

In exploring options to demonstrate ringing from reflections in transmission lines, Professor Eric Bogatin gets a greater understanding of debouncing circuits. Read on to see where his investigations led him.
