Know the Bandwidth Know the Bandwidth: How to Find Bandwidth of a Signal This article relates to both printed electronics and PCBs. I acquired my bandwidth design techniques working in PCB design, and later applied the same principles to my printed electronics design. In this article, I’ll explain my knowledge of bandwidth, and how I was able to apply it to both PCBs and printed electronics. Before going into details on bandwidth, I think it’s worth revisiting what we in electronics mean by the term “signal”. For me Read Article

PDN Analyzer Simulation of 65W Single IC LED Driver PDN Analyzer Simulation of 65W Single IC LED Driver In my last article, I designed a 65W LED driver for powering a 36V LED string at 1.8A. The small MSOP-8 IC on it is going to get quite warm, which makes me believe the power distribution network is worth simulating with PDN Analyzer. This will allow me to see if there are any spots that need optimization on the board. Anywhere I can reduce the current density in high-current areas to ensure a lower copper temperature will be worth the time Read Article
Living on the Edge (Rate) Rise and fall frequency Living on the Edge (Rate) — It’s All About Time and Distance The focus of this article is the clarify the origins of the phrase edge rate, what it really means relative to the design process and the best means for addressing it. 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
Any Angle Routing 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 Read Article
Image Processing Embedded Systems with Modular Hardware Image Processing Embedded Systems with Modular Hardware Image processing embedded systems can be deployed quickly thanks to modular design tools With advances in industrial automation, automotive technology, remote sensing, and much more, image processing is taking center stage in many embedded systems. Image processing with older video systems was difficult or impossible due to the low quality of many imaging systems with perpetual uptime. As a result, older camera systems could be developed for Read Article
The Shrinking Manufacturing Cycle The Shrinking Manufacturing Cycle Traditionally, an engineering cycle has been considered to be on the order of 18 months. That’s the time between generations of products, whether it’s a new processor or a new Internet appliance. Today, a company that operates on an 18-month cycle is considered slow within many industries. If you have a lot of competitors, their release cycles are likely out of phase from yours. For example, if there are three companies serving an application Read Article
Using Low-Volume Runs to Eliminate High-Volume Failures Using Low-Volume Runs to Eliminate High-Volume Failures “High volume” is a relative term. It depends upon what your business does and how many of a product you plan to sell. For one OEM, a minimum initial run might be 250K units. For another, 10K is the expected run of a product across its entire market life. One way to consider “high volume” is that it’s large enough to hurt your business if you make a mistake. Put another way, high volume is high risk. And given the stakes, you want to minimize this Read Article
