Signal Integrity

Browse our library of resources to learn more about pcb design and signal integrity.

Common Signal Integrity Pitfalls with Hans Klos Join us as Hans and Judy discuss the HyperLynx Connector tool, their upcoming webinar collaboration, and common signal integrity pitfalls. Read Article

Analyzing Crosstalk on FIFO and DDR4 Parallel Bus Interfaces Do you need to spot crosstalk on a parallel bus? Use a field solver that integrates with your PCB design and layout tools. Read Article

Preventing Ground Loops in Your PCB Design I think we’ve all been there. You buy that awesome stereo system only to hear that familiar humming sound in the background. When you take it back to the store the clerk blames the manufacturer. What components are to be considered a problem? The decoupling capacitor or ground wire? How about the bypass capacitor or ground loop interference? The stereo manufacturer will blame the component manufacturer and the component manufacturer can’t blame Read Article

High Currents and Higher Temperatures: PCB Design Tips for Heat Management I remember the first (and hopefully the only) time one of my circuits caught on fire. It started with the resistors and quickly spread to a nearby decoupling capacitor. Thankfully, the destruction was minor and most of the components were salvageable. Why did this happen you ask? No, this was not due to a short circuit. Very simply, I did not take into account the high current PCB layout. As electronics continue to be miniaturized, the thermal Read Article

The Advantages and Disadvantages of Active and Passive RFID Technologies When I’m designing a new PCB or product one of the hardest parts for me is choosing exactly which components I should use. It seems like every technology out there now has a different configuration to achieve the best performance. Even when you’re dealing with a fairly straightforward technology like radio frequency identification (RFID) circuit board there are a lot of flavors to choose from. While every type of RFID design label uses an active Read Article

Introduction to High Speed PCB Designing: How to Eliminate Crosstalk Recently at a wedding reception I was trying to talk to a gentleman who was sitting at the same table as me. Unfortunately there was a woman sitting between us carrying on a conversation with someone else sitting on my other side. With all the commotion of the reception in the background, conversation was difficult to begin with. Having another discussion taking place between us though made our conversation impossible. What we had was crosstalk Read Article

Customizing Performance-Based Electrical Design Rules in Altium Designer Electrical design rules go beyond manufacturing and assembly. PCBs also require electrical design rules that are based on a signals’ electrical behavior. Read Article

Expert Analysis of Measured S-Parameters Read to learn an introduction about S-parameter analysis. This article covers how to identify port maps, what insertion loss and return loss looks like, how the various S-parameters look in the time-domain, and some additional analysis techniques to use when data mining S-parameters.

LVDS to LVPECL, CML, and Single-Ended Conversions A lot is made of high speed interfaces for PCBs. Here’s how you interface between LVDS to LVPECL, CML, and other logic families. Read Article

How Load Capacitance on a Transmission Line Affects Your Signals If you ever read about transmission lines and integrated circuit datasheets, there is this seemingly mysterious quantity called load capacitance. This value depends on the geometry of the component lead connected to the transmission line, as well as the substrate material and distance to the reference plane on the integrated circuit die. When working with transmission lines, the load capacitance of a component has some important effects on signal Read Article

Microwave Cavity Resonator Emissions in Your PCB Layout Even digital designers need to worry about cavity resonant emission in PCBs. Here’s how your circuit board can act like a microwave cavity resonator. Read Article

MIMO Antenna Design and PCB Layout Tips Multiple-input multiple-output (MIMO) has become a more popular term now that 5G is becoming more publicized, but this term and the technology have been around for awhile. MIMO can be traced all the way back to research papers from the 1970s, and significant development was required before the technology could be commercialized. Recently, the drastic increase in wireless services direct to consumers and in offices has been enabled by MIMO. If you Read Article
