Controlled ESR Capacitors: Should You Use Them for Power Integrity?
I can’t think of a single product I’ve built that doesn’t require capacitors. We often talk a lot about effective series inductance (ESL) in capacitors and its effects on power integrity. What about effective series resistance (ESR)? Is there a technique you can use to determine the appropriate level of resistance, and can you use ESR to your advantage?

Microstrip Ground Clearance Part 2: How Clearance Affects Losses
If your goal is to hit a target impedance, and you’re worried about how nearby pour might affect impedance, you can get closer than the limits set by the 3W rule. But what are the effects on losses? If the reason for this question isn’t obvious, or if you’re not up-to-date on the finer points of transmission line design, then keep reading to see how nearby ground pour can affect losses in impedance-controlled interconnects.

What is High-Speed Design?
The primary source of high-speed problems is not due to high clock frequency but rather the fast rise and fall times of component signals. With fast edge rates, reflections may occur at the receiver side, and when the board routing is dense, crosstalk may become a problem. During this webinar, you'll sharpen your knowledge and develop new skills that you can use to design High-Speed PCB's more efficiently and effectively.

Composite Amplifiers and How They Give the Best of Both Worlds
There are many times where you need an amplifier with high gain, low noise, high slew rate, and broad bandwidth simultaneously. However, not all of these design goals are possible with all off-the-shelf components. Here are some points to consider when working with a composite amplifier design and how to evaluate your design with the right set of circuit simulation tools.

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.

Part 1: Why Your PCB Design Review Process Is Obsolete and What You Can Do About It
A PCB design review is a practice to review the design of a board for possible errors and issues at various stages of product development. It can range from a formal checklist with official sign-offs to a more free-form inspection of schematic drawings and PCB layouts. For this article, we will not delve into what to check during a design review process but rather look at how a review process itself usually unfolds and how to optimize it to get the most out of your time.

What is PCB Star Grounding and Why Would Anyone Use It?
If you look on the internet, you'll find some interesting grounding recommendations, and sometimes terminology gets thrown around and applied to a PCB without the proper context or understanding of real electrical behavior. DC recommendations get applied to AC, low current gets applied to high current, and vice versa... the list goes on. One of the more interesting grounding techniques you'll see as a recommendation, including on some popular engineering blogs within the industry, is the use of PCB star grounding.

Your Guide to PCB Silkscreen
Every PCB has silkscreen on the surface layer, and you’ll see a range of alphanumeric codes, numbers, markings, and logos on PCB silkscreen. What exactly does it all mean, and what specifically should you include in your silkscreen layer? All designs are different, but there are some common pieces of information that will appear in any silkscreen in order to aid assembly, testing, debug, and traceability

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.

Efficient Heat Dissipation with SMD Heat Sinks Keeps You From Dropping PCBs
In electronics, there is the possibility that your PCB can get pretty hot due to power dissipation in certain components. There are many things to consider when dealing with heat in your board, and it starts with determining power dissipation in your design during schematic capture. If you happen to be operating within safe limits in a high power device, you might need an SMD heat sink on certain components. Ultimately, this could save your components, your product, and even the operator.
