Electronics Product Design Today's PCB Designers Are Driving Electronics Product Design Professional designers know they play a fundamental role in the electronics product development process. Without circuit boards, all those semiconductors are a bit meaningless and they would not be able to provide the modern experiences we all enjoy. Even as PCB designers are so critical in the product development process, they still get the short end of the stick when it comes to product development tools. PCB design software is great for Read Article
6:07 Power Integrity Analysis in Your PCB Design Software Power integrity problems can abound in modern PCBs, especially high-speed boards that run with fast edge rates. These systems require precise design of the PDN impedance to ensure stable power is always delivered throughout the system. Without carefully considering the PDN impedance, you’re at risk of creating ripple and noise in the power distribution network when fast signals switch states. As more signals switch in large ICs, the result is the Watch Video

Plated Through-Hole Vias in mmWave PCBs Plated Through-Hole Vias in mmWave PCBs Plated through-hole vias in mmWave PCBs can ruin signal integrity in your RF interconnects if not implemented properly. Learn how to size and place stitching vias in this article. Read Article
virtual array calculation How to Calculate a Virtual Array in MIMO Systems RF and sensing systems that use MIMO functionality have some important design constraints concerning virtual antenna design and placement. In these systems, due to the need for finer resolution and higher transmit/receive gain, the trend has been to pack more antennas into an array for beamforming and the reception of low-level signals. There is a reason for this trend, and it relates to an important concept in antenna array systems. When Read Article

NVMe M.2 PCIe connector stubs A Brief Study of Stubs on a PCIe Connector Stubs are an important topic in high-speed PCB design, and there is a longstanding guideline that stubs should always be removed from all vias on high-speed digital interconnects. While stubs are bad for high-speed lines, they do not always need to be removed. What is more important is to predict the loss profile and frequencies, and to floorplan appropriately to try and prevent such losses. In this article, I’ll look at some simulation results Read Article
Cascaded transfer functions monte carlo Monte Carlo Analysis With Transfer Functions in Cascaded Circuits Pro circuit designers don’t just work with components in parallel and series when they design circuits. One way to build circuits is with circuit networks, which will have input and output ports. What happens inside each network can be analyzed in the traditional way (SPICE, by hand, etc.), but what is important is that the network maps an input voltage/current pair to an output voltage and current pair. Mathematically, this is quantified with a Read Article
3-port S-parameters How to Get 3-port S-parameters From a 2-port VNA Measurement S-parameters are fundamental quantities in signal integrity, and an ability to understand them from measurement or analysis is very important. If you have a 3-port network, like a power divider or circulator, it may appear that you must use a 3-port VNA to measure these S-parameters. It is always acceptable to measure between two ports, but you need to know what exactly it is you are measuring. As it turns out, you can use a 2-port VNA Read Article
