Jia, Song is an associate professor in the Department of Micro-nano electronics,  School of EECS. He obtained his B.Sc. from Harbin Institute of Technology in 1992, and Ph.D. from Peking University in 2003 respectively. His research interests include digital VLSI design, high speed and low power CMOS circuits, and memory design.

Dr. Jia has published more than 50 research papers, and most of them are published in top-tier conferences and journals, such as IEEE ISCAS, IET EL and IJCTA.

Dr. Jia has research achievements as follows:

1)  High speed CMOS circuits design: He proposed some new circuits scheme aiming to improve the performance of true single-phase clock-based dual modulus prescaler. The proposed scheme demonstrates best power efficiency and power-delay-product among referenced designs.

2)  Low power circuits design: He proposed novel array multiplier based on carry save adders. Some specific full adders in the adders array for partial products accumulation are simplified without any cost. By modifying the logic expressions of two special full adders, circuit complexity is reduced, resulting in decreased power dissipation and propagation delay.

3)  Novel TRNG design: A novel true random number generator with its entropy source based on a Boolean chaotic oscillator is proposed. The underlying mechanism of chaotic dynamics in Boolean chaotic oscillator is researched and a novel chaotic oscillator is presented. With the utilization of proposed entropy source, the new scheme can precede referenced designs in reliability, resource consumption, output bit rate, design simplicity and requirement of post-processing.
