Trace Resistance vs Trace Impedance When Trace Resistance Trumps Trace Impedance Trace resistance, trace impedance, plane resistance, and plane impedace: when do you need to worry about all of these quantities? Resistance and impedance both are important in small traces and fat rails on a PCB, both internally and externally. Sometimes a new designer entering the world of impedance controlled buses might think they have a trace resistance target, when really they have a trace impedance target. While in power electronics, we Read Article

package PDN How Does the Package PDN Impact Power Integrity? Component packages have their own power distribution network (PDN) that influences their operation and drives compensation in the PCB. Read Article
6:07 Power Integrity Analysis in Your PCB Design Software Power integrity problems can abound in modern PCBs, especially high-speed boards that run with fast edge rates. These systems require precise design of the PDN impedance to ensure stable power is always delivered throughout the system. Without carefully considering the PDN impedance, you’re at risk of creating ripple and noise in the power distribution network when fast signals switch states. As more signals switch in large ICs, the result is the Watch Video

Power Delivery System Design Power Delivery Systems Design This article is intended to define the new challenges and provide guidance in how to successfully engineer the Power Delivery System (PDS) so it meets the needs of new technologies. As integrated circuit technology allows for billions of transistors on a single IC, it has resulted in very powerful systems on a chip. This has made it possible to put the equivalent of supercomputers inside video games, cell phones, and a host of other products that Read Article
MLCC controlled ESR capacitor Controlled ESR Capacitors: Should You Use Them for Power Integrity? I can’t think of a single product I’ve built that doesn’t require capacitors. We often talk a lot about effective series inductance (ESL) in capacitors and its effects on power integrity. What about effective series resistance (ESR)? Is there a technique you can use to determine the appropriate level of resistance, and can you use ESR to your advantage? Like many answers to important engineering questions, the answer is “it depends.” One type of Read Article
LDO efficiency Testing the Limits of Your LDO's Efficiency The efficiency of your LDO isn’t a fixed value, but neither is your maximum current output. Read about your LDO efficiency curve to better see why LDOs have narrow operating ranges. Read Article
Ceramic Capacitors Maximum Voltage and Derating Ceramic Capacitors Maximum Voltage and Derating Operating just about any capacitor below its maximum rated voltage ensures a longer operating life. A capacitor's performance will degrade in response to the application of voltages approaching their rated limit and exposure to high temperatures. By choosing to limit the applied voltage, those degradation effects can be reduced. Ceramic capacitors are one of the most common types of capacitors that are in use today thanks to their compact Read Article
