Getting Started With PDN Analyzer
PDN Analyzer for DC Power Integrity
PDN Design for the PCB Designer
Power Integrity and Simulations with Heidi Barnes
What a very insightful discussion with Heidi Barnes of Keysight. In this episode, we will discuss all things simulations and power integrity in detail. We will dive into EM simulations, capacitor placement, Z, Y, and S parameters correlation measurements, and more!
Ebook: PDN Simulation and Analysis Guide
In this e-book, we’ll show how to create some fundamental PDN simulation models with SPICE, and how to analyze PDN impedance with industry-standard simulation programs.
Ferrite Beads and Transfer Impedance in a PDN Simulation
Ferrites in a PDN and transfer impedance are investigated in this article. We’ll show how ferrites in a PDN create problems for switching circuits.
PDN Impedance Simulation and Analysis in SPICE
PDN simulations can be performed in SPICE if you know how to properly model parasitics and inductive effects in power integrity analysis.
When Do PCB Power Plane Resonances Occur?
Do you know when a power plane resonance occurs in the PDN on a circuit board? We’ll examine when this occurs and what causes it.
What is Spreading Inductance?
The spreading inductance of a plane pair has a simple meaning, but it can be difficult to calculate. Here are some points designers should know about the spreading inductance of a plane pair.
A Guide to PCB Power Supply Layout
Follow this quick guide to using linear power supplies and switch-mode power supplies in your next PCB design.
Product Lifecycle Management in Electronics Manufacturing
This article will tackle the effective product lifecycle management (PLM) solution for electronics manufacturing. Read and learn how you can manage your electronics product development seamlessly and painlessly.
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
Ferrite Core Selection and Design Decisions
When designing a transformer or using a ferrite core inductor, you must use the correct design process, and there is no substitution for real-world final testing. Let’s look at the process.
Ceramic Capacitors Maximum Voltage and Derating
Operating just about any type of capacitor below its maximum rated voltage ensures a longer operating life. Such components’ 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, such effects can be reduced. Ceramic capacitors are one of the most common types of capacitors that are in use today thanks to their compact packaging
Resistor Derating to Improve Mean Time Between Failure
All resistors have a specified power rating that determines the maximum energy they can convert without its performance degrading or the component failing. Read now to learn more.
Methods of Circuit Protection
Overvoltage, overcurrent, and heat are the three most likely events that can destroy our expensive silicon-based components or reduce our product’s life expectancy. The effects are often quite instant, but our product might survive several months of chronic overstress before giving up the ghost in some cases. Without adequate protection, our circuit can be vulnerable to damage, so what should we do? Or do we need to do anything? For instance, if
Power supplies - Buy, Outsource, or Design
There is more stress on a power supply compared to most of the other parts of our design. Mark Harris addresses the most pertinent issues to consider and, in several places, adopt a checklist format for you to use. Read now.
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.
Should You Route Signals in Your PCB Power Plane?
Before you cut up your PCB power plane with signals, pay attention to things like impedance control power plane current capacity to ensure reliability.
How Total Harmonic Distortion Affects Your Power System
Total harmonic distortion is used to quantify the quality of power that reaches your electronics.
