Three UNIST ECE students have been recognized for their excellence in academic and research work at the 25th Annual International Samsung Human-Tech Paper Awards, held on February 13rd, 2019. Seyeon Yoo (Advisor: Jaehyouk Choi) received the Silver prize, Esan Jang (Advisor: Kyung Rok Kim) received the Silver prize, and Juyeop Kim (Advisor: Jaehyouk Choi) received the Bronze prize.

Seyeon Yoo received the Silver prize in the field of Circuit Design with a paper titled “A 140fsRMS-Jitter and -72dBc-Reference-Spur Ring-VCO-Based Injection-Locked Clock Multiplier”. In his work, he presents a new ring-VCO based injection locked clock multiplier using a triple-point frequency/phase/slope calibrator (TP-FPSC) that can remove all three root causes of phase errors. Using the proposed technique, this work achieved the world-best reference spur performance as well as ultra-low noise performance.

Esan Jang received the Silver prize in the field of Physical Device & Processes with the research named, “Monolithic active trantenna based on CMOS technology for ultimate high-performance terahertz wave detector”. In his work, he firstly presents a monolithic trantenna device which is convergence of transistor and antenna without feeding line for real-time large area multi-pixel terahertz imaging by CMOS technology.

Juyeop Kim received the Bronze Prize in the field of Circuit Design with the research on “A 76fsRMS-Jitter and −40dBc-Integrated-Phase-Noise 28−31GHz Frequency Synthesizer Based on Digital Sub-Sampling PLL” In his work, he presents a multi-band frequency synthesizer that can support existing cellular bands below 6GHz and new millimeter-wave (mmW) bands for 5G, concurrently. Among the state-of-the-art mmW-band frequency synthesizers, this work achieved the lowest noise performance.

Established in 1994, this competition recognizes an elite cadre of creative young researchers who through competition have demonstrated excellence in research. In this year, out of 1,920 excellent papers considered from high schools and universities, only 121 papers (81 from universities and 40 from high schools) were selected to receive the awards.
