Basics of Signal Integrity Analysis
How Important is your Microcontroller Clock Source
The type of clock signal you need to use for your microcontroller will depend mainly on the nature of the device it’s embedded in and its operating environment.
Copper Pour and Via Stitching: Do You Need Them in a PCB Layout?
When is it appropriate to use copper pour or via stitching in your PCB layout? Read our guide on copper pour and how it can be used properly with via stitching.

What is Signal Integrity?
Learn about the basics of signal integrity and how you can ensure your PCB layout complies with best practices for signal integrity.
ISM Bands Around the World
ISM bands (industrial, scientific, and medical) are parts of the RF (radio-frequency) spectrum reserved for general use by, as the name suggests, scientific, medical, and industrial devices. Their creation was in response to specific demands by these industries for access to the RF spectrum to perform functions without having to compete with the traditionally intensive users of RF, the communications, and defense sectors. The critical thing to
Choosing the Right Microphone for Embedded Applications
If you need to capture sound waves for your electrical device to process, you'll need a microphone. However, microphones these days have become very advanced, and there are so many options to choose from. While they are relatively small, they come with a broad range of options and technologies. They range from the relatively simple and popular condenser type microphones to state-of-the-art sound conversion solutions incorporating internal
How to Route a PCB
Learn about Routing a PCB and how to design traces to proper routing in any device. You can access the best PCB routing features in Altium Designer.
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.
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.
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
Comparing All Serial Communications Protocols
At the end of this series, we summarize the advantages and disadvantages of each type of Serial Communication Protocol available to transfer information between microcontrollers, data-producing, and data-processing peripherals, and other intelligent devices.
Serial Communications Protocols - CAN and LIN
In this article, Part 8 in our series of articles looking at different Serial Communication Protocols, we discuss the popular CAN and LIN protocols combined.
Bogatin’s “Practical Guide to” Book Series
Eric Bogatin, the Dean of Signal Integrity Academy, is here to talk about empowering PCB designers to become their own experts. Eric also shares the inspiration behind his new book.
Microstrip Ground Clearance: How Close is Too Close?
Make sure to account for microstrip ground clearance when using copper pour on the surface layer. We’ll examine what happens with microstrips, striplines, and coplanar waveguides.
Wideband Signal Analysis in Ultra-high Speed PCB Design
