icon Enabling Semiconductor Innovation:National Chiao Tung University Wins Numerous Macronix Golden Silicon Awards (09, 2014)
邊框

        The Fourteenth Macronix Golden Silicon Awards for Semiconductor Design and Application was held recently, and 50 universities and 352 teams entered the competition. The National Chiao Tung University won numerous awards and showcased its innovative and creative semiconductor R&D capacity.

        Under the guidance of Professor Ke-Horng Chen, Zi-Qi Huang from the Institute of Electrical and Control Engineering, and Xin-Hao Chen and Kui-Liang Lin from the Institute of Electrical Engineering, the Adaptive Speaker Power Load Management System based on the Human Auditory Model won the Bronze prize in the Application group. In recent years, thin and light designs have become the objectives for electronic product design. Internal speakers are limited by size and cannot fulfill high power and sound quality requirements. Therefore, the team designed a system that uses a Class D audio amplifier to increase volume and a DC–DC boost converter for dynamic power. The system can resolve the inadequate speaker volume, effectively control all inputted data, and demonstrate maximal output speaker power. In addition, the system can instantly detect the speaker’s dynamic impedance and load power, anticipating the speaker’s power output for the next time segment and enabling additional control to achieve optimal efficiency while protecting the speaker.
