Hassoune and O'Connor proposed a dynamically reconfigurable dynamic logic circuit (DRDLC) that generates Boolean functions by using double-gate (DG) carbon nanotube (CNT) FETs, which have an ambipolar property. O'Connor et al. proposed a DRDLC that generates 14 Boolean functions asing two Boolean inputs with seven transistors. Furthermore, DRDLCs that generates all 16 Boolean functions have been proposed. In this paper, we focus on the design of a dynamic logic circuit with n Boolean inputs. First, we show a DRDLC that generates the monomial Boolean functions. Next, we propose a DRDLC that generates the whole set of Boolean functions consisting of t terms or less. Finally, we report the number of Boolean functions generated by the proposed DRDLC.
