Researchers from the BASIC Lab (Bio-inspired Analog and Signal Processing Integrated Circuits) led by Professor Hyung-Min Lee at Korea University School of Electrical Engineering have achieved a significant milestone with the acceptance of three papers for presentation at the 2025 IEEE International Solid-State Circuits Conference (ISSCC). The ISSCC, held in February 2025 in San Francisco, USA, is considered the premier global conference for semiconductor integrated circuit design. This achievement reaffirms the lab's continued research excellence, following their success in 2024.

The papers to be presented at ISSCC 2025 include two in the Imagers, Medical, and Displays (IMD) track and one in the Power Management (PM) track, showcasing innovative research outcomes in display and power management technologies.

IMD Track Paper 1: A Real-Time Pixel-Compensated Source-Driver IC with Dual-Slope Error Detection and Multi-Channel Time-Multiplexing Compensator for Compact OLED Displays

Jaewoong Ahn, a Ph.D. student, proposed a "Real-Time Pixel-Compensated Source-Driver IC," which minimizes errors and enhances the stability of OLED displays through real-time pixel compensation technology.

IMD Track Paper 2: A Compact 10b Source Driver IC with Delta-Sigma Pulse Width Modulation for Low-Voltage Digital Interpolation Achieving 1884μm²/Channel

Junyeol An, an alumni, presented a "Delta-Sigma PWM Source Driver IC for Low-Voltage Digital Interpolation," which significantly improves the integration and performance of display driving circuits.

PM Track Paper 1: A 97.4%-Peak-Efficiency Always-Half-Inductor-Current Hybrid Bidirectional Converter with Adaptive Target Current Tracking for USB-to-2-Cell Bidirectional Power Transfer

Yunho Lee, a Ph.D. student, proposed a "97.4%-Peak-Efficiency Bidirectional DC-DC Converter" that achieves high-efficiency bidirectional power transfer between USB and 2-cell batteries.

ISSCC is attended by around 4,000 professionals from academia and industry each year, providing a forum for presenting and discussing the latest research in semiconductor design. Often referred to as the "Olympics" of semiconductor design, the conference is a prestigious platform for showcasing groundbreaking innovations. Professor Hyung-Min Lee shared his thoughts, stating, "This achievement is the result of our team's continued efforts in integrated circuit design. I look forward to contributing further with our research team through more innovative work."
