IEEE SSCS USTC Student Branch Chapter Hosts an Invited Lecture by Dr. Zhiyuan Chen T The IEEE Solid-State Circuits Society (SSCS) University of Science and Technology of China (USTC) Student Branch Chapter organized a talk on 22 October 2020 by Dr. Zhiyuan Chen, School of Microelectronics, Fudan University, China. The lecture was held at the Micro/Nano Electronic System Integration Center Laboratory, School of Microelectronics, with the assistance of Prof. Lin Cheng. Zhiyuan briefly discussed two integrated piezoelectric energyharvesting interfaces that do not have external inductors. Instead of relying on bulky external inductors with a high quality factor, as in the conventional approach that employs a parallel synchronized switch harvesting on an inductor, the first work proposes a flipping-capacitor rectifier topology to achieve the voltage inversion of the piezoelectric energy harvester through a reconfigurable capacitor array. This fundamentally preserves a fully integrated solution without inductors while achieving a high energy Prof. Lin (at podium) briefly introduces Dr. Zhiyuan.
