Figure 24: CPZ for the proposed CNTFET-fractional order CO with α=0.4
A comparatively larger CPZ is obtained on integrating fractional circuitry to CNTFET based CO spanning from 100Hz- 100GHz when analyzed using the same order (α=0.4) for fractional CO and CNTFET fractional CO as can be seen on comparing figures 24 and 20(a). The FOC of order α=0.4 gives a CPZ of 10MHz-10GHz in the fractional MOS based CO. Integrating CNTFET with FOCs results in a wider constant phase spectrum.
