Jonghoon Kim, a Ph.D. student at POSTECH’s Semiconductor Graduate School, and Professor Seun Shin’s Power Management and Integrated Circuit Systems Design Laboratory will present their semiconductor circuit design research results at the ISSCC 2025. Additionally, the research of Munjeong Cho, an Integrated Program student in POSTECH’s Department of Electrical Engineering, will be showcased through the ISSCC Student Research Preview (SRP).

Jonghoon Kim achieved a significant milestone by optimizing the parameters of the resonant current-mode wireless charging technology for implantable medical devices and multi-dimensionalizing the power receiving coil. His paper is titled “A Programming-Free Three-Dimensional Resonant Current-Mode Wireless Receiver with Real-Time Link-Adaptivity and a 0.904 cm³ Receiver Coil for Implantable Systems.”

Munjeong Cho, on the other hand, proposed a novel on-chip isolated offline RGBW LED driver with a single-stage and single-transformer winding that provides multiple outputs. He also designed a new controller capable of independent and precise current control.

ISSCC, often referred to as the “Olympics of Semiconductor Design,” is the highest authority conference in semiconductor circuit design, with over 70 years of tradition. ISSCC 2025 will take place from February 16 to 20, 2025, in San Francisco, USA.
