Analysis and Design of Current mode logic based on CNTFET

In this paper we present a current mode gate based on differential pair as an application of CNTFET. The proposed circuit has two output logic gates, one NAND and the other is AND. To simplify the circuit realization we use all CNTFET of same type, all with the same length and carbon nanotube symmetry indices (n,m). Complex circuits could be obtained in current mode replicating the differential pair CNTFET along the current path. The proposed procedure allows to simulate transfer characteristics from voltage input to current output but also from voltage input to voltage output. Moreover we can measure simulated power dissipation and delay times.
