Abstract

The 4th International Conference on Circuits, Systems and Devices (ICCSD 2020) which will be taken place in Nanjing, China on October 23-25, 2020, and will be held virtually due to the precaution to minimizing the ÑOVID-19 risk. The safety and well-being of all conference participants is our first priority, while we strive to offer many scholars and researchers this long-awaited conference to conduct academic exchanges with their peers.The COVID-19 virus has made our life very difficult, but we want to note that there are no barriers to science, as we continue to do our research works via modern technical means. The ICCSD 2020 has selected Zoom as the virtual platform. Each presenter will give a 15-minute talk and have a short discussion afterward. Before the conference, all of the authors will prepare and submit a video as a backup in case of unexpected technical problems.The submitted papers were reviewed by leading scientists in the areas of Circuits, Systems and Devices, and evaluated in accordance with their originality, innovation, technical merit and applicability. This year, the ICCSD 2020 program consists of many high-quality articles coming from several different countries around the world.We are grateful to the authors and the participants, as they are the key components for making possible this excellent forum to exchange research results and ideas. We also would like to express our sincere gratitude to our colleagues who have kindly volunteered in the paper review process. Special thanks go to the conference organizers and session chairs for their devotions in developing a strong technical program and enjoyable virtual experiences. It is our hope that the proceedings of ICCSD 2020 will result in increased collaboration among researchers in the fields and will help facilitating fruitful cross-disciplinary ideas.As always, we look forward to your continuing support of this and future ICCSD. Finally, we wish all of you good health and every success!Dr. Xiaoqing Wen, Professor, Kyushu Institute of Technology, JapanDr. Juin J.
