Grounding and Shielding

En savoir plus sur le livre

This book applies fundamental field behavior in circuit design and explores its connection to grounding and shielding requirements. It links electromagnetic theory to interference issues in electronic design, covering topics such as power distribution, mixing analog and digital circuitry, high clock rate circuit board layouts, and compliance with radiation and susceptibility standards. The author delves into grounding and shielding techniques, applying basic physics to circuit behavior. The sixth edition features updated material throughout the chapters and a rearranged presentation to align with current trends. New topics include vias and field control, capacitors as transmission lines, first energy sources, and high-speed designs with two-layer boards. The book illustrates how circuit geometry influences performance from DC to GHz, examines multi-shielded transformers for clean-power installations, and provides effective strategies for addressing noise in analog and digital circuits. It also discusses using conductor geometry to enhance performance, limit radiation, and reduce susceptibility across various hardware and systems. This updated guide is essential for circuit design engineers and technicians, as well as serving as a reference for professionals in the semiconductor device industry.
