Summary:
This letter describes a design methodology for an arithmetic logic unit (ALU) incorporating reconfigurability based on doublegate carbon nanotube fieldeffect transistors (DGCNTFETs). The design of a DGCNTFET with an ambipolarpropertybased reconfigurable static logic circuit is simple and straightforward using an ambipolar binary decision diagram (AmBDD), which represents the cornerstone for the automatic pass transistor logic (PTL) synthesis flows of ambipolar devices. In this work, an ALU with 16 functions is synthesized by the design methodology of a DGCNTFETbased reconfigurable static logic circuit. Furthermore, it is shown that the proposed ALU is much more flexible and practical than a conventional DGCNTFETbased reconfigurable ALU.
