SPICE Simulation Made Simple
SPICE simulation saves you critical time in the prototyping phase. Understanding your simulation interface makes it simple to analyze how your circuits work in different scenarios. Altium Designer provides an intuitive, dedicated interface to support your simulation verification, setup, and analysis directly in your schematic environment. You also benefit from growing support for popular model formats, as well as generic models, simplifying circuit definition and simulation.

Dual Rail Voltage Supply
The highest performing operational amplifiers often need a split supply with positive and negative voltages connected to the op amps supply rails. In this project, we’re going to be building a positive/negative dual rail power supply for a differential oscilloscope probe I’m designing. I’m making the power supply a separate project, as a dual rail supply is quite useful to have, and I’m sure I’ll find multiple uses for it in the future.

Library Importer Improvements (former Library Migrator)
Importing file-based libraries from your local computer or network drive to your Altium 365 workspace can be done using the Library Importer. Altium’s Library Migrator was renamed Library Importer—the feature’s name was changed to conform more closely to the tool’s purpose. Not only is its name new, but our team has also made several user experience improvements. We have updated the documentation to reflect this change.

How to Select Copper Foil for High-Frequency PCB Design
The PCB materials industry has spent significant amounts of time developing materials that provide lowest possible signal loss for products with RF applications. For high speed and high frequency designs, losses will limit signal propagation distance and distort signals, and it will create an impedance deviation that can be seen in TDR measurements. In this article, we'll look at the balance between copper foil losses and other types of losses in a PCB, as well as some strategies that are commonly used to overcome roughness.

What is Hybrid Beamforming?
In this article, we’ll look at beamforming implementation in an advanced method combining analog and digital techniques, known as hybrid beamforming. This method blends both digital and analog techniques to create multiple beams and thus reach multiple users with varying intensities. In the case of an RF imaging system or a radar system, hybrid beamforming in a MIMO technique also allows tracking of multiple targets with adjustable resolution.

Why Most Via Impedance Calculators Are Inaccurate
The problem with every via impedance calculator that I have seen is simple: they are incomplete or totally wrong. The “incomplete” part refers to a lack of context; these calculators can roughly reproduce a well-known estimate from a legend like Howard Johnson in his Digital Design textbooks. However, these calculators never provide insight into what they are actually calculating, or where the calculated via impedance is accurate. Keep reading to see why these calculators get it so wrong, as well as the context surrounding via impedance.

Buck Converter Simulation in Altium Designer
When designing high power circuits (usually very high voltage and/or current), you’ll need to create a regulator from scratch and place it in your PCB layout. It's also the case that you may want to model a real component using discretes in a simulation in order to qualify the system's expected operating regime. As part of buck converter design, you can easily run a buck converter simulation directly in Altium Designer’s schematic editor. Here’s how you can access these features in the newest version of Altium Designer.

Overview of the PCIe 6.0 Standard
Just as you get used to PCIe 5.0, they decide to release another standard! The newest iteration of PCIe is Gen6, or PCIe 6.0. PCIe 6.0 brings a doubling of channel bandwidth through introduction of PAM-4 as the signaling method in high-speed differential channels. This signaling method is a first for PCIe, and it’s an important enabler of the doubled data rate we see in the current standard. In this article, I’ll run over the important points in the standard and what PCB designers can expect when designing these channels.
