Why specialized PDN Cable® is Essential for your Power Integrity Impedance Testing

This short video discusses the feature set your cabling needs to get PDN impedance measurements correct. A coaxial instrument cable must do five things well: Accurately get the signal from the source to the instrument without distortion Provide the lowest possible cable shield resistance to minimize ground loop errors Maximize the shield attenuation to limit noise Be ultra-flexible so as not to rip the capacitors off the board Support environmental qualification testing Along

The Myth of Three Capacitor Values

By Eric Bogatin, Larry Smith, and Steve Sandler | March 3, 2020 “Many designs today include three different value decoupling capacitors, or when using just one capacitor, a small value like 0.1 uF. These recommendations are based on 50-year-old assumptions that do not apply today. It is time to reconsider these out of date, legacy design guidelines….” Click here to read the entire article #j2102b #powerdistributionnetwork #design #ESR #flatimpedance #powerintegrity #articles

What Makes PDN Cable Special

When Picotest announced the release of a new coaxial cable, designed specifically for power distribution network (PDN) applications this past month, the questions started coming almost immediately. What’s so special about the cable, why would a company like Picotest, which specialized is power systems test, develop their own cables and can’t I use any 50 Ohm coaxial cable? I think the most efficient way to respond to the questions is via a blog. So, if you are one that is

Characterizing and Selecting the VRM

The voltage regulator module (VRM) is at the foundation of power integrity, making proper selection essential. There are thousands of VRMs and VRM controllers available from many manufacturers. They are often selected based on size, efficiency, price, or a relationship with the manufacturer. This often leads to a poor VRM selection, requiring additional engineering resources, greater time to market, as well as higher BOM costs to correct the deficiencies. Even after the VRM o

Best Design Practices for Systems with PDN Noise-Sensitive Circuits Sponsored by: Rohde & Schwarz Abstract: Most of the power integrity focus is on high power devices, such as FPGAs and CPUs. Most power distribution networks (PDNs) also include sensitive circuits including LNAs, clocks, and PLLs, often even within the FPGAs. These sensitive circuits can be sensitive to microvolts of noise. The challenge is that over-designing

Predicting The Future: Industry Expert Discusses Three Disciplines Of PCBs

Many industry experts are speculating on what the future has in store for the three disciplines. One pundit is Steve Sandler, managing director at Picotest, who moderated a panel of seasoned engineers in a keynote event at DesignCon earlier this month. During this session, panelists gave their predictions on what the next five years holds for EMI, PI, and SI. Throughout his career, Sandler hasn’t shied away from making bold industry predictions, and has been spot-on about qui

The Quickest Path To Power Integrity

Two things became apparent to me during our recent series of 2017 Hands-On Power Integrity Workshops. First, the majority of attendees weren’t power supply designers, or even analog engineers. They were highspeed circuit designers and printed circuit board designers. In other words, they were power consumers. The second surprise was that there was much less interest in why the power integrity (PI) performance was what it was than how to correct it. For those engineers who wan

Designing High Current 48V to Core Voltage Converters

To reduce power consumption, easing cooling requirements, large computer designers are migrating from 12V to core voltage power solution to 48V to core voltage solutions. Some, but not all 48V to core voltage solutions being introduced do yield increased efficiency, but there are many other considerations and tradeoffs to wrestle with. The well-proven buck regulator topology is highly strained in this application, while new topologies may be perceived as a reliability risk. N

Measuring Sub-milliOhm PDN Impedance

High speed and portable electronics are still shrinking while power integrity demands continue to require lower power distribution network (PDN) impedance.  Measuring sub-milliOhms is difficult.  Getting low noise, sub-milliOhm measurements in very small circuits is a bit more difficult. The result,150 u?, is impressive. This article explores the test techniques involved in making the measurement.

Accurately measure ceramic capacitors by extending VNA range

Ceramic capacitors play an oversized role in circuit performance as a major contributor to voltage regulator control loop stability and power delivery network (PDN) impedance. When designing with these circuit staples, you need good impedance data over a wide frequency range. Proper measurement technique is the key to making accurate measurements. Here’s how to use two simple techniques that result in accurate, wideband, frequency measurements by extending the range of a vect
