Realization of Fractional Order Operations Using CNTFET Based Current Conveyors

Abstract— In Analog Circuits Low Power and High Performance are main Parameters so it has developed interest in designing carbon nanotube field-effect transistors (CNTFET) for their high mobility nature and lower nano-scale dimensions. CNTFET-based current conveyors are designed using integer order and fractional order oscillator, integrator, and differentiator and simulated in Cadence Virtuoso using a 32 nm CNTFET. FOCC (Fractional order current conveyors) oscillator have better frequency than integer order CNTFET current conveyors oscillators (66 MHz vs. 60 MHz) and they have wider phase zone (45–90° vs. 90°). while integrators and differentiators show better phase, broader bandwidth (100 MHz vs. 80 MHz; 120 MHz vs. 90 MHz). FOCCs also reduces power consumption (50 µW vs. 70 µW for oscillators).
