Anatomy of Latitude Part Two: "Thread with a Needle” in the context of energy
We continue to explore the magic of energy conversion in a PWM transducer. Why is it magic? Theoretically, as we saw in the previous section, the line stabilizer initially converts some of the useful power into heat, which makes the efficiency of the line stabilizer less than 100%, and it is expected for technical systems. Theoretically, in a PWM transducer this happens without losses, isn't that magic? A PWM transducer, like a tailor with

The Best Capacitor Circuit Simulator for PCB Design
A capacitor is a fundamental element in integrated circuits and in PCB design, and it’s hard to think of a circuit that doesn’t contain at least one capacitor. A capacitor’s behavior and interaction with other components in a circuit generally needs to be simulated to ensure the design will operate as intended. Capacitors can provide filtering, blocking, and power stability behavior depending on their use in a circuit, and a capacitor circuit

The Best Power Supply Circuit Design Tools With Simulation
From bench-top power supplies to power regulator circuits on embedded boards, designers often need to create a custom power supply circuit design and layout. These circuits sound simple to design, but it takes the SPICE-based simulation and verification tools in Altium Designer to create a stable, high-quality power supply circuit design. Altium Designer gives you much more than circuit design and circuit simulation tools; you can easily create

Data Management for Component Models in SPICE PCB Simulations
Simulation software is becoming more powerful as time goes on, but the simplest solutions are sometimes still preferable for many applications. SPICE simulations have been around for decades, yet their applicability to a wide variety of circuits and applications is not lost on anyone. With SPICE simulation tools being so popular, it’s only natural that they appear in PCB design software platforms. Devices continue to become more powerful and more

S-Parameter Measurements and Errors in Power Integrity
No matter where you look, it seems S-parameters never go away! They are mandatory tools for understanding some systems, such as an interconnect or antenna, while other network parameters can sometimes give a better conceptual understanding of electrical behavior. These parameters are normally reserved for signal integrity among electronics engineers, but if you look hard enough, you’ll find that S-parameters are also used for power integrity

Working Through Circuit Simulation for Free Often Won’t Work, Try Altium Designer
Electronic Design Automation (EDA) software provides the tools that support the design and analysis of electronic devices, systems, and printed circuit boards. Within this broad definition of EDA software, some companies offer free PCB design programs while others focus on schematic capture, mixed-signal simulation, Very Large-Scale Integration (VLSI) circuit design, and customizable design rule checking. While many EDA software applications

Making the Most of Your Crystal Oscillator
“Blindly” adopting what a crystal oscillator data sheet says usually results in adequate frequency stability. An oscillator requires the phase shift around the loop to be 360° and this total phase shift must be a precise and stable oscillation frequency.

How Load Capacitance on a Transmission Line Affects Your Signals
If you ever read about transmission lines and integrated circuit datasheets, there is this seemingly mysterious quantity called load capacitance. This value depends on the geometry of the component lead connected to the transmission line, as well as the substrate material and distance to the reference plane on the integrated circuit die. When working with transmission lines, the load capacitance of a component has some important effects on signal
