Reduce Common-Mode Noise in Your Power Supply with Impedance Balancing
Simple switching regulator circuits that operate in compact spaces, like on a small PCB, can usually be deployed in noisy environments without superimposing significant noise on the output power level. As long as you lay out the board properly, you’ll probably only need a simple filter circuit to remove EMI on the inputs and outputs. As the regulator becomes larger, both physically and electrically, noise problems can become much more apparent, namely radiated EMI and conducted EMI in the PCB layout.

What Causes Gibbs Ringing in High-speed Channel Simulations?
Designing high-speed channels on complex boards requires simulations, measurements on test boards, or both to ensure the design operates as you intend. Gibbs ringing is one of these effects that can occur when calculating a channel’s response using band-limited network parameters. Just as is the case in measurements, Gibbs ringing can occur in channel simulations due to the fact that network parameters are typically band-limited.

RF Power Supply Design and Layout Guide
One thing is certain: power supply designs can get much more complex than simply routing DC power lines to your components. RF power supply designs require special care to ensure they will function without transferring excessive noise between portions of the system, something that is made more difficult due to the high power levels involved. In addition to careful layout, circuitry needs to be designed such that the system provides highly efficient power conversion and delivery to each subsection of the system.

Methods to Protect your Circuit
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?

Getting Started with Revision Control in Altium 365
Ever since I started using Github and Google Docs, I fell in love with revision control. Instead of keeping multiple copies of essential files and time-stamping every revision, revision tracking information gets stored alongside the file. This environment works great for code, spreadsheets, and documents, and Altium brings these same features into PCB design.

Any Angle Routing: When Should You Use It?
EDA tools have come a long way since the advent of personal computing. Now advanced routing features like auto-routers, interactive routing, length tuning, and pin-swapping are helping designers stay productive, especially as device and trace densities increase. Routing is normally restricted to 45-degree or right-angle turns with typical layout and routing tools, but more advanced PCB design software allows users to route at any angle they like. So which routing style should you use, and what are the advantages of any angle routing?

Analyzing Crosstalk on FIFO and DDR4 Parallel Bus Interfaces
High-speed buses, whether single-ended or differential, can experience any number of signal integrity problems. A primary problem created by propagating signals is crosstalk, where a signal superimposes itself on a nearby trace. The industry-standard PCB design tools in Altium Designer® already include a post-layout simulator for examining crosstalk. Still, you can speed up crosstalk analysis in parallel buses when you use a powerful field solver.

Amplifier Stability at High Frequencies and Stray Capacitance
Any time-dependent physical system with feedback and gain has conditions under which the system will reach stable behavior. Amplifier stability extends these concepts to amplifiers, where the system output can grow to an undesired saturated state due to unintended feedback. If you use the right design and simulation tools, you can easily account for potential instability in your circuit models before you create your layout.

Working with Design Variants
The concept of design variants entails taking a single PCB design, and then on the assembly side, modifying specific components used in the design. Either by not installing, not installing, or choosing alternate components as replacements on a specific assembly to ultimately create different end products. In that way, you could support multiple product lines. This article describes the approach to working with variants.
