Yichuang Sun is Professor of Communication Electronics and leads the Communication Networks Group at the University of Hertfordshire in the UK. He obtained B.Sc. and M.Sc. degrees from Dalian Maritime University in China and was awarded a Ph.D. from the University of York in the UK. His research interests include analogue and mixedsignal circuits, testing and fault diagnosis, RF and communication circuits, and wireless communication systems. He has published over 120 papers and has coauthored a book entitled Continuous-time Active Filter Design, published by CRC Press, USA. Professor Sun has also been a Guest Editor for two special issues of the IEE Proceedings on Circuits, Devices and Systems. He is a Senior Member of the IEEE and serves as Vice-Chair on four Technical Committees including the IEEE Circuits and Systems Society, the IEEE Communications Society and the IEEE UKRI Section. He is Guest Professor at Hunan University of China.
