Reconfigurable logic based on tunable periodic characteristics of single-electron transistor

Single-electron transistor (SET), the most promising candidate for the post-CMOS era, can deliver high device density and power efficiency at reasonable speed. The THmnW logic gate is the basic element used in constructing a NULL convention logic (NCL) field-programmable gate array (FPGA), which is useful in embedded systems. We investigate the tunability of SETs and find that THmnW can be implemented with SET logic. By using a tunable periodic function implemented using SET logic, a novel method of flexibly designing THmnW logic gates is proposed. The simulation results show that the method can be used to flexibly design THmnW logic gates and can be useful for designing logic gates based on SETs. This method can be used to design structures such as FPGAs and programmable architectures more efficiently.
