TITLE : DETERMINATION OF CNTFET OPAMP PARAMETERS  
AUTHORS : Sridevi V      Jayanthy T            
ABSTRACT :

Carbon Nanotube Field Effect Transistor technology is the most promising technology for high speed digital and analog applications. This paper mainly focused on designing an operational amplifier using Carbon Nanotube Field Effect Transistor (CNTFET), since opamp is a widely used core element for analog and mixed signal systems. The various opamp parameters such as dc offset voltage, phase margin, common mode rejection ratio, slew rate etc have been determined and tabulated. The proposed CNTFET opamp exhibit significant improvements in speed and other major opamp parameters over the conventional opamp.

 
Keywords: CNTFET, CMRR, Differential Gain, Opamp, Slew Rate, Phase Margin
