Some Pre-layout Power Spectrum Analyzer PCB Tips in Altium Designer
Take advantage of your simulation tools before test and measurement. Here I want to expand a bit on the power spectrum analysis features in Altium Designer

. In a previous post , we looked at working with simulations involving a frequency modulated signal fed into a nonlinear component (an NPN transistor). In this simulation, we ended with the Fourier spectrum at the load resistor for various values of base voltage/current. In the time-domain

Open Source Software - A Moving Target
Open Source Software (OSS) is an attractive alternative to proprietary software platforms. There’s a lot to love about OSS. Lower cost is a primary decision driver for many companies. Others want to enjoy the freedom and flexibility to modify the software to their particular application requirements. Some companies don’t want to be at the mercy of the direction—or lack of direction—of proprietary software roadmaps. There’s also a lot to fret over

High Speed Routing Guidelines for Advanced PCBs
You can create this advanced board with these high speed routing guidelines for advanced PCBs Newer designs are continuing to get faster, with PCIe 5.0 reaching 32 Gb/s, and PAM4 pushing signal integrity and speeds to the limit. Proper interconnect design must account for the lower noise margins of advanced devices, impeccable power stability requirements, and much more to ensure signals can be received properly. With advanced devices running at

Load Line Analysis for Nonlinear Circuits in Altium Designer
If you’re in the business of analog circuit design, then you’ll likely need to run simulations of your system to determine its functionality. Linear systems are rather intuitive, even in the case where strong feedback becomes an important determinant of stability. With nonlinear circuits, this can get more complicated, and it’s not always easy to see how the system operates unless you have some experience with similar systems. Transistors and

SMPS Circuit Design: Which Switching Frequency to Use?
Power supply on a network switch Power electronics and switched-mode power supply (SMPS) designers should know that working with higher switching frequencies can lead to higher switching losses in your system. However, the push to miniaturize power supplies, and the components that go into them, compels designers to work with higher switching frequencies in their SMPS circuit designs. This then creates problems where switching losses and noise

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

How Absorbing Conformal Coatings Affect Your PDN and Radiated EMI
Signal integrity analysis and measurements go hand-in-hand I remember the first time I— back in my days of working with sensors —pumped nitrogen dioxide into a humid environmental chamber while evaluating a DUT. Over time, the surface of my copper leads slowly corroded as they sat unprotected in such a noxious environment. As my electronics experiment was living a double life as a chemistry experiment, I questioned whether to use a conformal

Power Integrity Measurements for Your Prototype Board
We often write about signal integrity and power integrity around here, but there is one area where we sometimes fall short: test and measurement. Both aspects of building a new device are critical for ensuring your board will work as intended and meets stringent performance requirements. With advanced systems, the level of testing and measurements required to qualify a prototype for full-scale production spans far beyond using a multimeter. Power

Signal Distortion in Your PCB: Sources and Solutions
Length matching for high-speed signals is all about synchronization... Signal distortion often gets a passing mention in many discussions on signal integrity and circuit analysis. As more networking products start running at higher speeds and use complicated modulation schemes, you’ll find that signal distortion becomes a serious problem that contributes to bit error rates. Distortion sources are cited as one of the primary bottlenecks preventing

Electronics System-Level Circuit Engineering Design in Altium Designer
Electronics system level design lets you focus on functionality and abstraction The day-to-day life of a PCB layout engineer is all about translating schematics into a real, manufacturable PCB. Before this can happen, designs begin at an abstract level that focuses on designing functionality. As the overall design process progresses, design requirements are made more granular, reaching the signal processing level and, eventually, the component

DC Analysis of Linear and Nonlinear Circuits in Schematic Design
These circuits can always use DC analysis If you’re working with a new design that involves some custom circuitry, it always helps to understand how the circuit behaves in DC. There is some merit to this, particularly if you are designing a custom power conditioning system, amplifier, equalizer, or other circuit. These circuits and many more require a range of analyses to evaluate their functionality, but the most fundamental of these is a DC

Agile Development and Testing: The Role of Simulations
Simulations can help you avoid repeated prototyping and testing Design, build, test; whether you are a hardware designer or a software engineer, you’ll go through multiple iterations when developing complex systems. The build and test portions are the moment of truth—when you find out whether your hard work will pay off. An important part of design, build, and test iterations concerns narrowly defining test cases and functionality requirements

Tools for Transient Signal Analysis in Circuit Design
You can perform transient signal analysis with any of these circuits with the right simulator. I still remember my first differential equations class. One of the first topics that was discussed was damped oscillator circuits and transient signal response, which arises in many different physical systems. A transient response in an interconnect and on power rails in your PCB is a source of bit errors, timing jitter, and other signal integrity
