Guest Editorial Special Issue on the 2021 IEEE International Symposium on Circuits and Systems

This special issue of the IEEE Transactions on Circuits and Systems-Part II: Express Briefs (TCAS-II) continues the successful tradition of the co-publication initiative started two years ago by the IEEE Circuits and Systems Society (CASS) to publish a selection of the best papers accepted for presentation at the IEEE International Symposium on Circuits and Systems (ISCAS), held this year in Daegu, South Korea, on May 23-25. As TCAS-II only publishes 5-page briefs, and hence both conference and journal versions of selected works would be largely overlapped, the papers included in this issue represent the only record published in IEEE Xplore and they will not appear in the Proceedings of IEEE ISCAS. Similar to other IEEE Societies, IEEE CASS pretends to shift the role of IEEE conferences towards networking events as well as a scientific discussion opportunity, rather than putting the emphasis on the conference paper publication itself.
