Which Capacitor Types Should You Use?

Which Capacitor Types Should You Use? Capacitors are used in far more applications than just bypassing noise, and there are many more types of capacitors than just ceramic and aluminium electrolytic. Read Article

Reflecting on Your Design, Part 2, What Do Reflections Do to a Signal?

Reflecting on Your Design, Part 2, What Do Reflections Do to a Signal? In part 1 of this article, I described what transmission line reflections are, how they are created and what the resulting waveforms look like. This part of the article will discuss what reflections do to a signal. Figure 1 is a typical 5V CMOS driver driving a 50-ohm transmission line that is 12 inches or approximately 2 nanoseconds long. There is a CMOS receiver at the end of the line that is a tiny parasitic capacitor. For these purposes, it Read Article

Optimizing Power Consumption

Optimizing Power Consumption Power efficiency—energy efficiency if you’re a purist—has become perhaps the highest-profile aspect of system design. This is especially true for IoT applications where a device may need to operate for years on harvested energy or a cell battery. Thus, a critical stage of design is power optimization. Typically, the first stage of power optimization is setting the power budget. For example, the system spec might state that the device has to be Read Article

Power Integrity Analysis for Your Power Delivery Network

Power Integrity Analysis for Your Power Delivery Network Designing PCBs to have stable power output is as much an art as it is a science. Power integrity analysis and simulation is all about verifying a design will deliver the required power, but also that the delivered power will be stable. This idea that a power supply might not deliver stable power is not necessarily related to the power supply, it's related to the design of the PDN on the PCB. The structure of a PCB, the elements used to store and Read Article

Simplify Schematic and PCB Designs by Highlighting Nets

Better PCB Routing - How Altium Highlight Nets Regardless how many PCBs I design, I always find myself having to regularly review network paths on schematics layer and trace routes on PCBs. The complexity reminds me of a maze where only one path is the right one for a particular network. It is imperative that all the connections are accurate as errors made here will come back to haunt you later in the form of redesigns. The best way to ensure network accuracy is by isolating it so that each Read Article

Voltage Regulators and How to Plan Your Power Budget with PDN Analysis

Voltage Regulators and How to Plan Your Power Budget with PDN Analysis With my first buck regulator design, I had been given a power budget for the circuit block and I had to take into consideration what it was supplying and what topology I’d use. I considered efficiency to remove heat from the enclosure and I wanted to avoid using a heat sink. I also wanted a robust engine, a regulator to keep on working when the CPU, memory, and other utility circuits were exercising their might. I decided on the buck regulator Read Article

High Currents and High Temperature: PCB Design Tips for Heat Management

High Currents and High Temperature: 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

History of Wave Soldering: Developing the Wave Soldering Process

History of Wave Soldering: Developing the Wave Soldering Process It is often said that the sun rises in the east and sets in the west. Of course, Copernicus long ago dispelled this misinterpretation. Even so, when I am on the road early in the day and the horizon is continually getting brighter I always get a sense of excitement coupled with uncertainty as to what the day will bring. With the speed at which technology changes today, what the future will bring is a constant concern for engineers and designers Read Article

Learning Current Density: Don’t Pop the Balloon

Learning Current Density: Don’t Pop the Balloon One area of PCB design that probably does not get the attention that it deserves is current density. Current density in a PCB trace is much like the pressure in a balloon. You want to squeeze as much air into the balloon as you can, but if you put too much: boom! The same is true of PCB traces many times. We want the traces to be as small as possible yet carry the most current possible, and if the trace carries too much: boom! For PCBs, that boom Read Article

10 Symptoms of a Bad PDN At face value, DC power integrity seems to be a simple enough topic -- you just need to make sure that every component on your PCB has the power (current and voltage) it needs when it needs it. But that’s just on the surface. TOPICS IN THIS SOLUTION What is power integrity? What’s the problem? Symptoms WHAT IS POWER INTEGRITY? The new reality is a bit more complicated.
