Design of Binary-to-Quaternary Converters based on CNTFET Transistors

In order to connect two binary and quaternary systems, it is necessary to use binary-to-quaternary (B2Q) and quaternary-to-binary (Q2B) converters. These converters convert numbers from logic 2 to 4 and vice versa.  In this paper, we designed a new binary-to-quaternary converter circuit using CNT transistors. In this circuit, the Power Delay Product (PDP) has been reduced to14.59% and 15.39% compared to best previous works (Ref [22] and Ref [23]). Also, this circuit has better driving ability and temperature stability than best previous works. The simulation results using Stanford's 32 nm CNTFET model in HSPICE software are at a voltage of 0.9 V.
