Applications of Carbon Nano Tube Field Effect Transistor (CNTFET) Based Operational Amplifier

Carbon Nanotube Field Effect Transistor (CNTFET), one of nano electronic devices, is a transistor with its channel made of carbon Nanotube and it is designed to provide the solution for scaling process and the possibility of coexistence with current silicon technology. CNTFET-based devices offer high mobility for near-ballistic transport, high carrier velocity for fast switching, as well as better electrostatic control due to the quasi one-dimensional structure of CNTs. This paper describes the work on modeling, performance benchmarking for nanoscale devices and circuits using carbon Nanotube field effect transistors (CNTFETs), with the aim of guiding nanoscale device and circuit design. The integrated circuit operational amplifier (op-amp) is an extremely versatile electronic device, which is encountered in a wide variety of applications ranging from consumer electronics (stereos, VCR’s) to complex commercial applications and industrial controls. This paper also simulates the applications of Carbon Nanotube Field effect transistor based operational amplifier.
