As Ray Kurzweil’s predictions edge closer to reality, AI continues to transform engineering, education, and daily life. Follow along as Signal Integrity Journal Technical Editor Eric Bogatin examines the risks and rewards of technological evolution while reflecting on the role of humans in an AI-driven future.

The IPOSIM from Infineon Technologies AG is widely used to calculate losses and thermal behavior of power modules, discrete devices, and disc devices. The platform now integrates a SPICE-based model generation tool that incorporates external circuitry and gate driver selection into system-level simulations.

Power GaN 2025, powered by Yole Group, provides a detailed look at the market growth, technology trends, and strategic shifts shaping the gallium nitride power device industry. 

Designed for point of load power rails in commercial space systems and other extreme environments, the new device is particularly well-suited for distributed satellite power systems and digital processing payloads, including FPGA and ASIC systems.

Infineon has launched the CoolSiC™ MOSFETs 1400 V G2 in the TO-247PLUS-4 Reflow package. The devices support higher DC-link voltages and enable improved thermal performance, reduced system size and enhanced reliability.

Infineon is further advancing on its path to become a leading GaN powerhouse and bolstering its position as the world’s leader in automotive semiconductors by introducing its first GaN transistor family qualified to the AEC standard for automotive applications.

Continuously improving efficiency, power density, and signal integrity of power conversion from the grid to the core is therefore critical to advancing computing performance while reducing total cost of ownership. To address this need, Infineon is launching the OptiMOS™ TDM22545T dual-phase power module, the industry's first TLVR module specifically designed for high-performance AI data centers.

In this article, Tyler Huddleston explores causality in relation to signal and power integrity simulations. He reviews how causality affects time-domain simulation fidelity as well as how non-causal s-parameters can result from real measurements and simulations. Learn about how non-causal data can be avoided and the consequences of using a non-causal model in time-domain simulations.

Infineon Technologies AG introduces a 12 kW reference design for high-performance power supply units, specifically designed for AI data centers and server applications.

Infineon has announced the strengthening of its existing collaboration with Delta Electronics, Inc., in the development of state-of-the-art high-density power modules capable of enabling vertical power delivery to AI processors in hyperscale data centers.
