Circuits and Devices

Circuits and Devices at EE

This domain is an essential core area in EE as well as in EPFL. It deals with the design and experimentation of electronic devices and their integration into circuits and systems. The activities are not necessarily limited to conventional silicon-based technologies, but cover a wide range that includes novel technologies. The circuits and systems area has several core strengths : the ability to model complex physical phenomena and devices that are used for various fundamental functions (such as storage, signal amplification, and switching); the ability to abstract the time-domain and frequency-domain operation of complex systems and networks using a consistent mathematical framework; and the ability to create a strong link between theory and experimental results.

Building on this foundation, the circuits, systems and devices area is uniquely positioned to further grow and systematically address new challenges such as nanoelectronic devices and circuits.

Activities in the Electrical Engineering Institute also touch upon the physical layer of communication systems, including optics and electromagnetics (EM), and EE labs are very active in areas like computational electromagnetics and in the design and miniaturization of antennas, sensors and other primary EM radiators.
