The IEEE Circuits and Systems Society (IEEE CAS) is a society of the Institute of Electrical and Electronics Engineers (IEEE). In the hierarchy of IEEE, CAS is one of almost 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 first meeting of the IRE Professional Group on Circuit Theory was on March 20, 1951. After the IRE and the AIEE merged, the IRE Professional Group on Circuit Theory became the IEEE Professional Technical Group on Circuit Theory on March 25, 1963. In 1966, the group changed its name to the Group on Circuit Theory, and in 1973 became the IEEE Circuits and Systems Society.
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 grants annual awards, scholarships, and more. The IEEE Circuits and Systems Society’s annual awards program recognizes member achievements in education, industry, technological innovation, and service. Winning an award from any of these societies is considered a huge technical accomplishment, achieved only be the top professors at top universities, and typically the subject of a press release.
The Society organizes, sponsors, and co-sponsors many conferences every year (64 conferences in 2006).
One of the technical committees is the Computer-Aided Design Technical Committee (more commonly known as CANDE, for Computer-Aided Network Design). The purpose of CANDE is to promote research and best practices in the development and use of computer-aided design software in the design and test of microelectronic circuits and systems.
The Technical Committee on VLSI (TCVLSI) is a constituency of IEEE-CS that oversees various technical activities related to computer hardware, integrated circuit design, and software for computer hardware design.
