Buck Converter Size vs Frequency

Buck converters work with two energy storage devices, the inductor and capacitor. In such a switching power supply, the inductor is responsible for storing and transferring energy between input and output. The purpose of the capacitor is to smooth the output voltage by filtering the ripple current generated by the

Power Delivery Networks for High-Performance Circuit Boards

Note: this article assumes a foundational knowledge of AC circuits. My previous article introduces important topics such as reactance, frequency vs. impedance, and resonance. This article is more about theory and applications than math since it is assumed that the reader already understands the math and underlying concepts. I highly

AC Circuits for Practical Electronics: Theory

Introduction In the world of electronics, AC circuit analysis is often associated with power systems and devices directly powered by an AC source, like household appliances and industrial machinery. However, the importance of AC circuit analysis extends far beyond these applications. Even in devices that rely solely on DC power

Termination, Reflections, and Signal Integrity: Foundations

Most embedded computing systems use some form of high-speed logic signal. Whether it be a memory interface such as DDR4, a communication bus like PCIe, or even USB, these signals must be terminated to work properly and avoid reflections. Reflections contribute to all sorts of signal integrity issues. The effects
