USB PD: Power Delivery for Your Next Project
Since its introduction in the late 90s, the USB standard has never ceased to grow in popularity. Multiple revisions of the standard have kept it relevant to the growing demands of data delivery, which has made it the ubiquitous choice for electronic devices. There has been a growing trend toward USB being a power delivery interface with data, rather than a data interface that can supply power, as the 1.0 specification originally intended. To

PCBs vs. Multichip Modules, Chiplets, and Silicon Interconnect Fabric (2023 Update)
An article in the September 2019 issue of IEEE Spectrum claimed that silicon interconnect fabric, a method for connecting chiplets on a multichip module or advanced package, would eliminate PCBs and bulky SoCs for many applications, specifically motherboards. It's now 2023, and no one seems to have ditched PCBs yet; the demand for PCBs remains as strong as ever and is still projected to grow at double-digit CAGR. This is despite the expected

Filter Transfer Function and Pole-Zero Analysis in Altium Designer
I remember spending hours on circuit analysis problems in my electronics classes, and I learned to analyze all sorts of filter/amplifier configurations by hand. The circuits were usually tractable with Ohm’s law and Kirchoff’s laws, as long as there was no feedback in the circuit. Circuits for advanced applications, such as wideband or multiband matching circuits for RF components, can quickly become difficult to analyze by hand. But as the

Understanding Your PCB Netlist File
Understanding Your PCB Netlist File There are several different ways that PCB netlists are used at various stages of the electronics development process. Netlists may have different purposes and may have unique data formats, but they all provide a similar function; they list the connections of an electronic circuit. This is important for a variety of fundamental tasks in electronics and PCB layout design. Your PCB netlist file is used graphically

Use Altium Designer’s IPC® Compliant Footprint Wizard to Make Unified PCB Library Footprints
Altium Designer’s IPC
®
Compliant Footprint Wizard facilitates accurate PCB footprint generation for each component in Altium Designer. The footprint generation feature in Altium Designer overcomes some of the biggest productivity bottlenecks in other CAD systems, such as OrCAD/Allegro and PADS. Instead of manually creating every footprint from scratch, use the footprint generation tool in Altium Designer and our suite of automated library

Frequency Modulation Simulation in Altium Designer
When working with analog signals, you need to ensure your device is operating linearly in order to prevent problems like harmonic distortion during operation. Nonlinear interactions in analog devices lead to distortion that corrupts a clean analog signal. It may not be obvious when an analog circuit clips just from looking at your schematic or datasheets. Instead of tracing through your signal chain manually, you can use simulation tools to get

Long Live EDA: Modular System-level Circuit Engineering Online
Modular instruments like this are much easier with online electronics design software If you’re familiar with the electronics design automation (EDA) industry, you’ll find plenty of similarities. These important software platforms have been the mainstay of electronics development since the 1980’s. Although there is plenty of differentiation between different products, as well as various levels of integration, these platforms have always seemed

Getting Started in Altium Designer: The Schematic
A schematic is a way to record an idea. Schematics are drawings or diagrams that are used to communicate electronic ideas to others. You may have never thought about it, but anyone who understands electronics can look at your schematic and understand your idea, no matter what language they speak! Schematics are a universal “language” for recording and sharing electronic ideas. Here’s the official definition from IPC-T-50 (Terms and Definitions)

Unique Flex Termination Methods
I think it is important to know that basically any connector you would select for rigid printed circuit boards can also be assembled to a flexible circuit. Traditional thru-hole and SMT connectors, high density circular connectors, D-subminiature connectors, pin and socket connectors, leaded and unleaded, are all options to consider with flexible materials. That said, I am going to veer slightly off topic with the caution to NOT forget to review

Embedded Optical Interconnects in PCBs for Ultra High Speed Design
Most PCB designers—except those that work on optical transceivers—are probably not aware of the coming revolution in silicon photonic integrated circuits (PICs), electronic-photonic integrated circuits (EPICs), and greater proliferation of embedded optical systems outside of telecom. Applications outside of telecom (for example, military and aerospace systems) that require massive data transfer rates already make use of fiber optics for embedded
