Proper Plane Design Techniques

02/12/2026 | I-Connect007 Editorial Team
Continuing our discussion from the November issue of Design007 Magazine on proper plane design, Kris Moyer, an instructor for the Global Electronics Association, shares techniques he teaches his PCB design students to use. When it comes to plane design, there are several challenges with modern high-speed designs. Planes, or more specifically, mirror/return paths, are critical to proper controlled impedance transmission line design. Additionally, to mitigate high-speed switching “noise,” the use of planar capacitance is now necessary and critical.

Empower Launches High-Density Embedded Silicon Capacitors for AI and HPC

02/11/2026 | Empower Semiconductor
Empower Semiconductor, the world leader in powering artificial intelligence (AI)-class processors, today announced the launch of three new embedded silicon capacitors (ECAPs™), designed to meet the power integrity demands of next-generation AI and high-performance computing (HPC) processors.

Power Integrity: Effective Decoupling Radius

11/26/2025 | Kirk Fabbri, Siemens EDA
Power delivery on modern systems is an important and challenging problem facing hardware designers. These challenges are even more apparent as device operating speeds and current demands increase. Modern FPGAs, processors, and other devices feature fast switching currents and demand precise voltage levels.

Beyond Design: Micro-ohm Power Delivery Network for AI-driven GPUs

11/18/2025 | Barry Olney -- Column: Beyond Design
The evolution of modern processors, marked by faster edge transitions, reduced output impedance, and increasingly complex bus architectures, has significantly augmented the demands on PCB infrastructure. These challenges are compounded by AI-driven graphics processing units (GPUs), which require exceptionally high-power delivery at ultra-low operating voltages, placing greater stress on power integrity and layout design.

Beyond Design: The Fundamental Structure of Spectral Integrity

10/21/2025 | Barry Olney -- Column: Beyond Design
Impedance can be characterized in both the time and frequency domains. In the time domain, it influences how electromagnetic energy propagates through interconnects, affecting signal integrity and waveform fidelity. In the frequency domain, AC impedance determines how well the network can suppress noise and deliver clean power at a range of frequencies. AC impedance shapes how power rails respond to transient loads.
