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.

Is your via impedance calculator accurate?
Blog
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.

Checking for Creepage in High Voltage Designs

High voltage devices have leakage currents that propage over the surface of the board. In such devices, it's important to consider not only the standard gap between the two topological elements, but also the shortest possible path between them, taking into account cut-outs and holes. With Altium Designer 20, you can check for creepage using the new creepage distance rule.

SPI vs. I2C: How to Choose the Best Protocol for Your Memory Chips

One of the common implementations of SPI and I2C in a PCB layout is as a protocol for reading and writing to an external Flash memory. Flash chips are a very common component in embedded systems and can offer high capacities of non-volatile memory up to Gb values. When choosing a memory chip, you'll want to match the application requirements and functionality with the bus speed you need for read and write operations in your memory chip. There is also the matter of the type of Flash memory you'll need to access (NOR vs. NAND).

Tips & Tricks: Board Shape Creation

Being able to design a board in your ECAD environment doesn’t mean that it is manufacturable in real life. You have to make sure your CAD representation won’t have any problems in the real world by taking some precautions. For example, there are certain areas that need to be free of components and have specified clearances like your board edge. This webinar will help you get acquainted with the creation and modification of your board shape so that you can ensure manufacturability.

Is There an SPI Trace Impedance Requirement?

There is no SPI trace impedance requirement? The reality is that SPI lines only start to need impedance control when the length of the interconnect becomes very long. And because there is no specific impedance requirement in the bus, you have some freedom in channel design and termination. So what exactly qualifies as “very long” and when is some termination method needed? We’ll break it down in this article.
