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

Efficient Heat Dissipation with SMD Heat Sinks Keeps You From Dropping PCBs In electronics, there is the possibility that your PCB can get pretty hot due to power dissipation in certain components. Whenever a component reaches an extreme temperature that goes beyond a component's safe operating range, its lifetime will be greatly reduced or the component may fail immediately. The heat-producing component being defective means the entire PCBA will need to be scrapped. There are many things to consider when dealing with Read Article

How to Simulate a PCB Design Get started with a PCB simulation and learn how to simulate a PCB design. Make sure you use the best PCB simulation software in Altium Designer's unified environment. Read Article

What Causes Gibbs Ringing in High-speed Channel Simulations? Gibbs ringing is both a measurement artifact and a calculation artifact that arises in band-limited channels. Make sure you understand how this arises due to transform and convolution operations. Read Article

How the Gibbs Phenomenon Produces Measurement Artifacts The Gibbs phenomenon is a measurement artifact that can be mistaken for real signal integrity problems like ground bounce, ringing from reflections, or resonance on short lines. Read Article

Buck Converter Regulator vs LDO for DC, AC, and RF: Which is Best? For small, low-current loads, LDO is usually the best option. What about a buck converter? Learn more about choosing between a buck converter vs. LDO in this guide. Read Article

Which Types of Opto-Isolators Are Right For Your Signal? An opto-isolator is an electronic device that can be used to pass information between a diode without passing an electrical current. Because there is no need ot directly pass voltage or current between the inputs and outputs in an opto-isolator, these components can be used to provide electrical isolation two regions in a PCB. Opto-isolators act as a protection mechanism, ensuring that harmful electrical currents cannot flow across the device. In Read Article
