Abstract: The main objective of this paper is to describe the work on modeling, performance benchmarking for nanoscale devices and circuits using Carbon Nano Tube Field Effect Transistors (CNTFETs), with the aim of guiding nanoscale device and circuit design. First, a compact model has been developed for MOSFET like Carbon Nanotube Field Effect Transistor (CNTFET) which posses high fabrication feasibility and superior device performance. The design aspects of a high performance CNTFET based operational amplifier are presented. This CNTFET op-amp is used for the realization of various active filters and the simulation studies have been done using Hspice.
Keywords: Active Filter, Carbon Nanotube Field Effect Transistor, Hspice, MOSFET, Op amp.
