Abstract
This paper presents an overview of the state of the
art on carbon-based circuits and systems made up of carbon
nanotubes and graphene transistors. A tutorial description of
the most important devices and their potential benefits and limitations
is given, trying to identify their suitability to implement
analog and digital circuits and systems. Main electrical models
reported so far for the design of carbon-based field-effect devices
are surveyed, and the main sizing parameters required to implement
such devices in practical integrated circuits are analyzed.
The solutions proposed by cutting-edge integrated circuits and
devices are discussed, identifying current trends, challenges and
opportunities for the circuits and systems community1
