A comparative analysis of power consumption has also been performed. It can be seen from Table III that the power dissipated is the least for CNTFET based CO. When tail current is varied from 5mA to 500nA for the case of CNTFET based oscillator, there is a significant reduction in power consumption. Analysis of individual fractional and CNTFET topologies have been performed and compared with conventional MOS topology. It has been observed that a significant decrease power consumption is achieved in the CNTFET based CO in comparison to the conventional MOS based CO. This is attributed to the unique characteristics of CNTs as discussed above.

To tap the advantages of both CNTFET and fractional order domain, a CNTFET based fractional order CO is designed and analyzed. Figure 23(a) shows the circuit diagram of the proposed fractional order CO, with α=0.62. Figure 23(b) shows the transient analysis of the proposed CNTFET based fractional order CO.
