Physics-Guided Active Learning and Geometry-Aware Electrothermal Screening of Semiconductor Devices: A GaN Case Study

Physics-Guided Active Learning and Geometry-Aware Electrothermal Screening of Semiconductor Devices: A GaN Case Study 150 150
Author(s): Ayoub Sadeghi, Leonid Popryho, Inna Partin-Vaisband

Abstract:

Exploring high-dimensional semiconductor device design spaces under coupled electrothermal constraints remains challenging, particularly in 3-D heterogeneous systems with tightly coupled electrical, thermal, and integration requirements. Conventional TCAD-driven exploration is physically accurate but computationally expensive and offers limited insight into governing parameters. This work presents physics-guided active learning trigate optimization (PALTO), …

Author(s): Heng Ma, Huajun Zhang, Yuyan Liu, Marco Berkhout, Qinwen Fan

Abstract:

This article presents a cost-effective, fully integrated shunt-resistor-based in-line current sensor that delivers high linearity and strong PWM rejection, enabling precise current measurement and control in dynamic driving systems like robotics, imaging, and audio. To mitigate the self-heating of the on-chip shunt resistor, which degrades linearity, a location-based thermal compensation …
