The IEEE Circuits and Systems Society is a society of the IEEE. It is also known by the acronym IEEE CASS. In the hierarchy of IEEE, the Circuits and Systems Society is one of close to 40 technical societies organized under the IEEE's Technical Activities Board.
From the IEEE CAS web site, the field of interest of the society is defined to be
"The theory, analysis, design (computer aided design), and practical implementation of circuits, and the application of circuit theoretic techniques to systems and to signal processing. The coverage of this field includes the spectrum of activities from, and including, basic scientific theory to industrial applications."
The Society organizes many conferences every year and operates local chapters around the world. It coordinates the operation of several councils, task forces, and technical committees.
The Circuits and Systems Society oversees the publication of eleven periodical magazines and scholarly journals:
IEEE Transactions on Circuits & Systems I: Regular Papers
The Society organizes, sponsors, and co-sponsors many conferences every year (64 conferences in 2006). A list of them can be generated here.
